Baking shadows are incorrect in animation

  • Hi everyone,


    I have a problem with the visibility of lights and shadows in the interiors. When doing an animation - the first frame renders reasonably correctly, but when the camera moves away - you can see that the shadow burned in the first shot remains only in the place of the first frame.


    Below I paste 1 frame of the animation and 1 second later.


    Does anyone also have a similar problem?

    Until yesterday, the same scene worked perfectly without this error.


    Thank you, bye!


  • Hi gemodele , and thanks a lot for your post.


    You've already received a dedicated detailed message from one of my colleagues through the submitted support request.


    To sum it up briefly for anyone who stumbles upon this thread: This basically caused by the fact that the GPU is entirely overloaded here since the project uses 4k-8k textures, as well as a 16k skybox, all with an NVIDIA GeForce GTX 1070 Ti 8GB of VRAM.


    In this case, the amount of VRAM and power of this card is not sufficient and odd shadow behavior as seen here can occur (among other issues potentially)- We, therefore, recommend downsampling these textures, using a lower-sized skybox as well as following the additional steps which don't need to be detailed here since it's specific to your case.

  • Hi there,

    Thank you for your help, but I have solved it other way.

    First, I have decreased most of the highres texture but it didn't change anything at all (please be aware, that I've been using highres textures since years with Enscape, and there was no problem with it).

    Then, I just cleaned up all the materials in the scene (except 16k HDR as sandbox), and then it worked fine again, so I new it was something with materials.

    After cleaning each material separately, I found out that the problem was with emmisive light materials. Don't know why, but it works fine again.


    Thanks anyway!

    Bye!

  • Can you elaborate on what 'cleaning each material' means? How does 'clearning' the material relate to a problem with emissive materials? Tnx

    By "cleaning material" I meant deleting it from the scene library.

    When I deleted all of my emissive materials, suddenly error disappeared. Afterwards I made a new light material, and the error didn't reapear.
