Issue with Forest Pack Lite 3ds Max Arnold Rendering On Max 2021

(1/1)

Jack:
Des anyone have any suggestions.

I've upgraded from 3ds max 2019 which I used ForestPack v 6.3.1 to
3DS Max 2021, for which, i've installed ForestPack lite 7.1.2  to test it out before I repurchase

ForestPack renders with scanline fine...when I render with Arnold it crashes Max with the following applicaiton error prompt: "application error
An error has occured and applicaiton will now closed"   

Here is the final entry from the 3DS Max log file: "
2021/10/29 18:50:47 DBG: [23272] [23140] FOREST 7.1.2 'Forest001'(R): Starting BuildMesh(0)

I can get it to Render if i set the render mode to "Meshes" instead of Automatic but then i run into various memory render issues and no render outputs.  Especially if i render with GPU.

I didn't have issus with 2019 Max GPU  Arnold Render.   



Max to A Version 5.0.1.4
Arnold: 7.0.0.0 [47ab20b9]

Nividia drivers up to date and Max is the newest version.

iToo:
Arnold 7 is not compatible with Forest 7.1.2. We must recompile our plugins to support it.
A beta of Forest Pack Pro will be available in the next days (Forest Lite will take more time).

Please, downgrade MaxToA to 4.3.4. That should fix the problems:
