I'm having a problem when rendering with path tracer, the shadow near the camera show some vertical black lines. I tried to adjust shadow bias and nothing changes. Attached is the same scene rendered in raster and path tracer.
Hi ,
Usually, this type of issue occurs when your model is very far from the origin point in Twinmotion/your original CAD program, which can decrease accuracy of textures and other model data. If you move the model in the CAD program closer to the origin point, then the issue should be eliminated after re-importing.
If that's not the case, we may need to take a closer look at the file. If you could submit a bug report here with a copy of your Twinmotion file, that would allow us to investigate further. When sharing your file, please use the Resource Collector in Twinmotion's Edit menu to package and compress your file with all texture data.
Best,
Raghib
