Title: Corona + Forest pack leafs preset
Post by: Claudio1985 on 2019-05-22, 10:27:45
Hi everybody,

I'm experiencing some trouble with the entire preset leafs library from Forest pack.

Since I added leafs to the scene, Corona became so slow: 1hour e 20 minutes for calculating second GI and 13 hours for 4 render pass.
I checked the leafs' material but nothing seems to be strange.

Anyone with the same issue?

thanks in advance

Ps: Corona3+Forestpack6.1+max016

Sure that it is caused by the FP object(s)? Are you able to see the effect in a scene with only one FP object + preset assets? If yes, would you mind to attach such a scene (with erased "forest_templates" layer)? Do other presets behave normally? BTW: The render times you mention are not very meaningful if we cannot see at least an image of the scene.

But especially the long GI calculation rings an alarm bell here. How many rays/s do you have when GI calculation runs? I see you are using Max2016. Do you use any VectorMap in your scene by chance?


Good Luck

I guys,

I spent few hours cleaning up the scene.

Actually the problem was determinated by a corona bump converter running in a material with displacement. I used the map to convert a composite diffuse into bump. I don't know if I was doing something wrong or if the map got some conflict with the displacement.

Anyway, Forest leafs preset are fine

Thanks for reply

Can you try to recreate bump converter issue in a separate scene? If you'd suceed, then please report it in bug reporting board.
