As you can see below, some white artifacts created in this render. This is the Rhino render with some ‘standard’ plants that came with LD.
I think it may be a bouncing limit problem. Since the render ray crosses a lot of overlapped transparent faces it might be reaching the max bounces limit for the render.
In the case of Rhino render you can change this limit in the Document properties, under the Render page:
Try to increase the max bounces values. Does it solve the problem?
Thank you so much for your response and the suggested fix Albert.
Unfortunately, I have dismantled the scene already so i cannot test the theory however I’m confident your explanation would solve the issue. If I run into the issue again Ill try to confirm your fix and post it here for others to reference.
