Flickering Bump Map

Introduction to Maya - Rendering in Arnold

This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Hey,

I am in the middle of a dynamics showing cloud/smoke from the rear of an asteroid is it hurtles through space.

But I seem to have hit a snag....

Asteriod 5 Mov (Use WMP to play)

the bump map seems to flicker as it plays, as if every frame has a difference bump map setting. I am not using default lighting, but 2 area lights to light the scene. motion blur has been added also (default settings)

Does anyone know why this is happening? Is it the lighting type I am using?

Thanks

PS. Here's a still image

you may need to parent the shader node to shape node to prevent this from happening. Either that you maybe baking the material that contains the bump?

mhcannon,

Thx for the advise...

I have removed the textures and have redone it. and tidied up the cloud particles and lengthed them.

The new texture setup seems to have sorted the issues I faced.

Here is a link to the new animation...

Having sorted this I now know it was a fool thing to do to apply a 3D texture as a bump map, once I used a 2D one everything was OK suprisingly...

DO'H
