Defining an object's transparency results in loss of color (it becomes white)

Defining an object's transparency results in loss of color (it becomes white)

Hello!

I have a problem that I can't seem to be able to fix.

This was a project work for an university class last semester. I had to fully model an item of choice, I should have already finished it, actually it is finished since long, but I can't properly render it, because when i define the transparency of the main shaft, it becomes white and buggy. I asked my teacher multiple times, but he couldn't give me a solution, as far as I've noticed his opinion is that fixing it would take too much effort and so he told me to just render it as it is (being white and buggy), and he'll accept it, cause I've topped the class regardless in quality of work.

The thing is, not being able to fully finish this drill is bugging me, even so because this would be my demonstration of value when applying for a job in the future, and I can't just go there and show them a buggy product.

So apart from the story, I can provide 2 test videos, one without defining the transparency at all of the main shaft, then the second with a defined 100% visibility. Also pictures to show how I defined the transparency.

If somebody could give me some tips on how to fix this, I'd really appreciate it.

I use PTC Creo Parametric 3.0 M070 student version.

Thanks in advance,

Hi,

I tested simple animation created by commands Trans @ Time (see attached video) in CR2 M070 and CR3 M100 and it works well.

What OS?

What Graphics Card?

What Graphics Card Driver?

Is this in an emulator on a Apple computer?

‌Thanks for the replies, unfortunately i cant watch the video from my phone bút ill check it out as soon as i get to my pc.

I Use a laptop, lenovo Y50-70 from 2014.07, specs are:

intel 4710hq processor

gtx 860m grahics

i dönt know the driver but ill check asap

windows 8.1 os.

I Think the problem originates from some kind of error in the process of defining the transparency, őr because i have 2 main shafts installed at once (Same assembly, but different joints)

ill upload pics and/őr videó from the final assembly too asap só you can see the real picture, still this is just a test assembly but the same thing occurs

Hi,

you can also create some test data for me and upload them using How to Attach a File to a Discussion Reply procedure.

I can load your data and run your animation on my PC.

Sorry for replying so late, I had a really busy week, also I had to switch my focus from this project to more urgent things. Due to that I had to quickly finish it, render it and burn it on CD to hand it in as the previously mentioned school project. Honestly, it looks like crap, and it makes my hearth ache, knowing how much work I've put into it, and how terrible it looks as of now (due to visibility bugs, and also a little modification in the event time tables would help it, and speed reduction, etc)

Regardless, this is the final video, I think you can see most of the visual bugs that I couldn't fix. I plan on perfecting this model for later use, I'd do it when I need practice and have free time for it (tho I dont think I could progress on my own from this point regarding the visual bugs).

As for the test data, could you please help me with that? I mean like be a bit more specific, as of now I don't know what you mean and even if I did, I wouldn't know how to create it.

Thanks!

Re: Defining an object's transparency results in loss of color (it becomes white)

Did you change the value or leave it at 0? Your images show the value at 0.

Re: Defining an object's transparency results in loss of color (it becomes white)

Right, I've changed it as the last picture shows, its only that I pressed print screen before i've changed the value. Sorry, my mistake.

Re: Defining an object's transparency results in loss of color (it becomes white)

Also check your part appearances. One thing that could be happening is if the part is an imported part from step or iges the colors that are applied my be the issue. You may need to clear the appearances from the models and re-apply them.

Re: Defining an object's transparency results in loss of color (it becomes white)

I see a lot of complaints about rendering with the GTX860m.

Nvidia targets this to DirectX, and I am pretty sure PTC still depends on OpenGL. Maybe different drivers are required. I can't tell which because people who say they fixed the problems with new drivers never say what drivers worked.

You can try re-rendering with OpenGL turned off. Try adding the config option "graphics win32_gdi" to config.pro and restart.
