I am having issues with the path tracer in simple and complex scenes. In the visualization and the rendered image I have this black lines, like the tracer did not go over the entire image.
New Pc, I updated everything. I do not seem to find a solution.
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.
