1 pointIts a tough problem. I am not really sure what to do. I am looking at this https://docs.arnoldrenderer.com/display/A5AFMUG/Export+Settings#ExportSettings-ExportVertexColors I think this is just for exporting in maya though. I see what you were saying about plugging in the color set. The Max equivalent would be this I think. https://knowledge.autodesk.com/support/3ds-max/getting-started/caas/screencast/Main/Details/2a01656f-b2f5-49ba-80ce-abebcfb22faf.html?_ga=2.108247938.1617953730.1590558748-1820435255.1590558748 The above link has a video tutorial. are you selecting "export vertex colors" within the arnold attributes for the mesh.? It might be a good question for the forest pack forums. I have never tried to work with a forest pack object outside of max. I'm sorry I cant be of more use. If anyone else has had experience here please post!
1 pointYou could definitely animate a flower opening. Something you might try to make things a little easier on yourself would be to introduce a dummy path. It would just bee an invisible path on the end of the parent of the petal paths. You would tie the animated flower modifiers to its length. This way the plant could grow and the flowers would animate after the plant was done growing. Fruit growth can also be made in a similar way. I have a pretty in depth tutorial on plant growth here( below ). It is a little boring but it should take you through everything you need.
1 pointHi! Here's an excellent plugin to create proxy objects for animated vegetation, so you can have a light model in scene and play the animation smoothly on viewport. And the best of all: it's compatible with GrowFx objects! Q-Proxies 3dsmax plugin And this is a great tutorial showing different techniques you can use with this plugin and a GrowFx tree with a wind animation: Q-Proxies Tutorial: Creating Proxies for Animated Vegetation
