Artifacts when rendering images #3

Closed Avuerro closed 2 years ago

Avuerro commented 2 years ago

Hi,

I'm trying to render images from the 3D Shapenet models, however the resulting images have artifacts. Initially, I thought this might be solved by implementing backface culling, however, unfortunately the problem still remains. I have tried to follow the instructions as stated in the papers on light field network and continuous scene representations, e.g. radius = 1.3, specularities and shadows disabled and environment lighting energy set to 1.0

These are my results: example_1 example_2

compared to renders from the same model in the SRN Cars dataset example_1 example_2

I would greatly appreciate it if you could point me into the right direction to render the images without the artifacts

Solved, apparently Blender was not able to find the texture files.

@Avuerro Sorry to bother you. I also encountered this problem, the rendered results are not good as SRN, and the colors also seem not correct. Could you help me how to solved this problem. 图片 图片

@SeaBird-1995 I'm sorry it has been quite a while, I can't remember what I did to solve it and I do not have access to the code I used back then. Unfortunately, I don't think I can be of any help

The issue is not textures. I fixed it by making it a larger resolution (512x512 instead of 128x128) then downscaling after rendering to 128x128. It just looked pixelated to me. file 000003
