How to do a realistic and world class render in Creo?


How to do a realistic and world class render in Creo?

Dear Creo Users,

I have been trying to create a part which I like to present infront of office members. So it should be visually attracting. I have tried with render window, render region and render set up  and appearance gallery but cannot get the realistic look I want. Any suggestions or tutorials on Creo Render will be highly appreciated.

With regards,

Soumya Bhattacharya.


Unfortunately, I believe the answer to this is to export the model and use another rendering package.  We've had excellent results using Keyshot; I believe Blender is also very capable.

Although apparently Creo 4 has something based on Keyshot integrated with it...

Re: Rendering in Creo.....Sux!

Hello Soumya Bhattacharya

if you got Photolux licence try following link:

Creo Advanced Rendering video tutorials

Don´t know better rendering tutorial...

Hi I am using Creo 2.0. Will I be able to create a good looking render in Creo 2.0?

Thanks Milan Bonka for sharing tutorial video.

With regards,


The answer is simple. Don´t even try. It is amazing how Creo is one of the worst softwares for rendering. Creo 1-2-3-4... Same thing.

A long time ago I wished PTC would pick up POV Ray or Blender interfaces. Sigh.

I have to agree with that, Creo is behind the in the rendering department.

Any rendering I do , I export the models and use a package that use NVidia Iray render engine, and I get good results.

Would you believe that this is a Cad model, I rendered out at home on .



That is a very nice render, thanks for posting!

Once you completed the geometry, scene, lights, etc.. How long did it take you? (I mean, once you click ¨Start Rendering¨) What NVidia card are you using? It is a really cool scene!

I should keep my mouth shut here but it's so hard and I have so much to say on the subject.  but who am I anyway?

I learned 3d Studio just as it was ported from the Amiga to a PC in 1991 and started rendering in Alias in 1993 and started on Maya in 1998 and I could make a thread of render tools inside those tools that are far superior.  Perspective is often the root of all problems which is how i would suggest any effort to encourage better render tools from you PTC Product Line managers. Their perspective may be that "we are only rendering product' and as a tool most people...."  that's how i get it sometimes.  To me that is a mild perspective problem.

If you want better renders in Creo you need to escalate and project a great deal of anxiety and hopefully your with a large-ish company.  Render is simply not a high enough priority for PTC.    Mental Ray is an impeccable tool that Creo currently uses.  I use mental ray in Maya so it's easy to compare what is missing in the Creo version.   Although comparable to SW Creo Render, programmers don't expose enough of the code to have it compete w/ that of Maya.. Workflow is a bit updated over wildfire but if you ask me it's not there yet.   At least Decals place over NURBS surfaces and there are many positives.    If that tool could get much better (probably thru looking closely at other tools like Maya/Max etc) as the benefit might be that early adopters might latch on and push the renders making the product sell better.    Suggestion, learn Maya and join the Technical committee and use all your charisma to bite kick scream.  That's what I did and won a little.  I think I have found rejuvenated enthusiasm and may participant this January.

I have to agree, trying to expect Creo to be the complete all in one package, is asking to much. The rendering in Creo is really a bare bones option that you would expect in an engineering software program, and can give a respectable result, but it is limited  by the fact that it is a sub feature of a cad package .

That's why I use an outside program that was dedicated for just rendering, the level of tweaks and adjustment offered in outside program to control the output is vast, and can change the result greatly.

I use a package that uses Iray and the level of detail in the textures, shadows, lighting, camera is by far, much more than you can expect a plug in of a cad package to offer, but is a steep learning curve in what you have to set to get very good results.

As for the time to render out the above image, I let it run til it finished and was about 20 min.


don't forget layers.  Imagine looking into the an eye of the person next to you.  It is wet complete with rectangular reflections of the lights from the room.  Layers are a different perspective for many people.  You can layer up materials in Maya to present dirt or rust parametricaly or various colors in a human eye.

I often just do a simple render onto a white background for technical documentation here, this is where the default Creo render engine works well. Any thing I do for sales department, I do in the dedicated render software.

At the moment, in Creo 4 F000, we don't even have the basic render option. I hope this is fixed in later build codes

I disagree with some things here.

Creo is a CAD engineering software, that´s ok. But, did you saw the video of the ARX of Creo? Those renders are as a bad as the Creo render engine, and they use to put them as the "best way to show your products¨.

I mean, what really annoys me is not the render itself, is that PTC tell people how impressive their renders are, when in fact, is one of the worst I believe. Now they are making augmented reality renders, as for me, that´s like taking a huge mistake to another level.

The key word here is perspective and i need to get this out.

If you know me personally i am an aggressive person.   Some take me wrong others are encouraged by me. From racing, climbing bicycling to Creo & Maya.  For me it's all about learning and how fast can one improve from day to day. Delta.  We might complain that people holing us back and often it is ourselves that hold us back the most.   In the most polite way possible i simply want to encourage people to learn new things and be aggressive about it.  It may change ones perspective.

Perspective is everything

To me perspective is everything.  I come from the perspective of engineering.  However to be aggressive, I made a push in the late 90's to learn other tools for rendering like Alias & Maya.  I even invited the then product line manager for training in those tools.   My now 15 years later perspective is from a movie rendering tools perspective.  An industry where their tools are used in every movie since Jurassic Park ,Spider man and star wars.

World Class Renders

The title posted was 'world class' and that quite frankly leaves our engineering tools in the dust. Not to complain I try to be proactive and make intelligent arguments and like in politics you try to utilize all your charisma to persuade others. It may be hard to imagine w/ an engineer's perspective how to make render tools better.  Remember decisions are all based upon what we know not what we don't know. 

Ill try to explain w/ respect to Maya renders.  A material in any modern render tool is a color w/ respect to how light reflects off it.  Is the spectacular highlight round and diffused at the ends making the material look dry looking or is the highlight rectangular making the material look wet and layers like a thick layer of automobile aftermarket paint job?  So yes creating a room in with a large format LDR image where that material reflects rectangular out of the material would make the object look wet and more glossy.

In Maya we can layer up these materials on top of each other creating effects only possible in Creo with multiple renders then later adjusting those renders using opacity layers in Photoshop.  Which by the way aggressive Photoshop experience is always a must w/ post production of renders.  (2 day class gets you to that skill set)

Some years ago Design Engine did a series of renders of an Indy Car for the Ad Agency representing Penske Racing then basically Marlboro w/ out the Marlboro signage.  The Indy car was molded in WF4.0 and you can download that Pro/E model from our website BTW  m We did the import OBJ into Maya and did the render in Maya with a blue sky and red car as you can imagine even had the PTC logo on the mirrors.   So the initial test renders we noticed the car was pink not red (no Pink in Marlboro land and thru much problem solving we realized the blue sky combined reflecting into the red made pink.  In Maya there is a setting in the material to not accept reflections or to accept reflections from some other object.  We quickly molded rectangular lights above the car and assigned a bright white luminescence material to those rectangle lights to obtain a rectangular spectacular highlight that made the red material pop as masterful rectangular speculator highlights of glossy wet red paint. (look into the eyes of you significant other and notice the layers in their eye from the pupil to the blood vessels to the glossy wet layer.  The camera in some of the renders went right thru the light that we made invisible to the camera but not invisible to the red paint material.

Another example that might be more applicable to product with respect to ground reflection.  In Creo rendering there is no way to control the percentage of reflection on the floor plane.  When a user first learns to render they usually apply floor reflections 14% or higher when in reality a highly polished floor would rarely present past 2% in these examples I present a screen capture of the same bike seat (not even a render) and muddy up the reflection some.  In other renders Ill had some noise to the floor to add swirls also in a layer in Photoshop.

Screen shot default

screen shot with the reflection blurred a bit using Photoshop to soften the reflection.  Just posted this

These techniques are not avail in SW either LOL however, I have pushed for some of these types of items into now 10 years ago Pro/E and got laughed at.   I can handle it and I get it as most Engineers will never use this.   I'm a bit upset but that's why I don't bother helping change peoples perspectives.  It's like politics, you can try but your not going change another perspective so easy.  It's easier to just make fun of the politicians than to try to make meaningful change.

The PTC Augmented Reality stuff is cool fast and impressive for sure.  I suppose possibly fueled by Iron Man making changes in a mid air version of PTC Creo Augmented Reality/Windchill product.  Not sure that needs to be rendered to a photo-real level yet.    overall PTC Creo is an impressive sweet set of tools and PTC is run by some extremely smart people.  If anyone wants to participate from a professional level and try to inflict change, i suggest to join a technical committee and get fully engaged!

For all the reasons stated I would look into Keyshot.   CREO 4.0 comes with a lightweight version of keyshot out of the box.
