Question

Need to prevent a Spotlight from shining through solid objects. I have selected shadows but the light still shines through. I even put a plate which has non transparency properties right in front of the spotlight and it shines through it.

Need to prevent a Spotlight from shining through solid components.  I have selected shadows but the light still shines through.  I even put a plate which has non transparency properties right in front of the spotlight and it shines through it onto other components behind the plate.  I have all other lighting (default, back, etc) turned off.

      Hi,

      please tell us what version you are using. Also attach a picture and upload Creo data, if you can.

      Hi,

      in case that you are active customer I suggest you to open Case at PTC Support.

      I did test in CR2, CR3, CR4 ... your problem is reproducible in interactive shading mode in all versions.

      In CR4 I tested light behavior in Render mode with Keyshot renderer ... in this case result was correct.

      In CR2, CR3 I was not able to produce correct result with Photorender/Photolux renderer -  I think because I do not have the appropriate knowledge .

      My guess:

      • in interactive shading mode Creo is not able to solve lighting realistically
      • realistic results are produced in rendering mode, only

      Maybe Vladimir Palffy can explain the situation.
