Right, been bashing my brains out late last night, and cant sort out this problem on the attached image. I seems like bubbles, but they are not, and threw the animation, they are static. The glass is a dielectric shader( glass physic actually), with light persictance of 30, ior 1.5. Liquid is same, only ior 1.333. Why do I get this?
I tried to use raytrace for fluid (dielec for glass), but no result. Use raytrace for glass (dielec for fluid), no. Tweeked the liquids ior out and other col parameter (dont have max here now) to make it a dielectric-dielectric interface (reading book rendering with mental ray). As the mesh is generated by realflow 3, mabe the mesh normals are not good, so i swich ignore normals. Nothing. They fade a bit away is when i use max sampling 128 and use contrast on red to 0.001. Takes ages, so i am hope this is not the only solution, as I need the animation done with this.
Wow, that is the longest question I have ever typed..well, hope some one can help, many thanks...
