Hello,
I wanted to suggest a setting that I’m personally feeling the need for whenever I use SpeedTree. By default there are 3 colour variations in the materials settings, meaning to use any colour variation you have to commit to 4, including the base. I feel most of the time I can get away with 2-3 colours and it would be great to have an option of adjusting the number of variations to achieve the desired number. As it is, I barely use the setting as a result. I know you can remove the undesired colours in Unreal, if you manually change the material slot inputs, but removing this unnecessary step would be great.
Another suggestion is adding a colour blend option for these variations. The current option seems to be normal blending, so it removes a lot of the texture detail. Maybe like photoshop layer blend modes - multiply, screen, overlay etc.?
Thanks for taking the time to read this feedback. Hope it was useful, and ont previously suggested.
