forest animation follow geometry with corona

[Pierre]

Hello,
I can't make the growth of a plane (with follow geometry method) .  The rendering of the animated objects without forest works but the rendering of the forest is invisible. . Do you know how I can solve this problem?
I attached my file made with 3dsmax 2020.3 + Corona 5 hotfix1 + Forest 6.2.4
Thank you for your help

Hi Pierre,

There seems to be a problem with the implementation of our API in the Corona 5 Hotfix 1 - though the preview behaves correctly having the Follow Geometry mode selected, for rendering the "Frame from Map" mode behaves like the "Follow Geometry" one. I'm attaching the modified scene.

Let me add, that for developers of render engines that don't have an SDK (like Corona, Octane, Thea Render and others) we provide an internal API written in C++ for the 3ds Max SDK. Then they use this data to generate the instances directly in their render engine and therefore the final implementation of Forest's features depends mainly on the way how it's done for that specific render engine.

Best regards,
