Particles shimmer and disappear

[Tengiz]

Hi

I have problems with TyFlow with Vray and Corona Render . I create particles for some shape. If they are too small (camera moves far from the object), some of them start to desappear and appear on different shots, but they shouldn't. As a result I receive bugs on hole video. In Vray particles desappear, in Corona they shimmer.

Zoom in on the problem areas and render them...do the particles still shimmer? Then it's a rendering/sampling issue that doesn't have to do with tyFlow. If the particles still disappear, let me know.

In VRay set the Min Subdivs to 2 or maybe 4 ... or more if required. This should help when you have renderable stuff which appers smaller than 1 pixel in the rendering. But its not a tyFlow issue, I think.

Thank you for your advice!

I changed renderer for Corona and received shimmering on small particles. In V-Ray the problem was solved by increasing min subdiv =6.
Can you suggest me what can I do in Corona?

Sry, never used it.
