Title: Animation glitch using Forest Pack Pro
Post by: maciek.c on 2018-02-05, 23:11:01

I'm not sure if it's a Corona or Forest Pack problem, but since I've never run into a similar issue with Vray+Forest Pack combo I decided to post it here.
The problem is that random frames in animation seem to loose Forest color/tint  information. It affects all forest color maps in the scene. Below I attach 2 consecutive frames - first one is ok, the second one lost given color tint.
The error is completely random, it does not appear every nth frame, etc.
Corona 1.7, 3dsmax 2016, Forest Pack Pro 5.4.1

Hi,

How exactly is the tree material made?
Is there some kind of network rendering involved here?
I think it would be best if you could share your scene with us, or at least an isolated part of the scene, where the problem can be reproduced. You can use our uploader at https://corona-renderer.com/upload

As i look carefully, it looks like if the green trees are going redish, maybe a "color correction" missing plugin problem ?

I am not able to reproduce the flickering here. The trees always have the same color, and strange enough it is always the more _yellowish_ color, not the green one visible in your provided example.
I tried with FP 5.4.0 and 5.4.1. Rendered the 3 frames, and also some more to make sure it's always the same.
I'll contact iToo about this.

@maciek.c is this report still valid?
Can you comment on my last message? Can you explain what is the expected result here? The trees having various colors, having just the more green color, or having just the more yellow color?
