Good afternoon, I did not find the plant I needed in the Megascans library, I wondered how to create the necessary material, similar to those in the Megascans library. I didn’t quite understand how to create Albedo, Opacity, Normal, Glossness, Specular, Subsurface and AO maps for a plant leaf.

I don’t quite understand how to fill the entire space of the Albedo texture so that there is no transparency and the background, as in the screenshot, is filled with color.

  You can use the opacity map to cut out each component on every map and move them where you want them, but you won't want to rotate anything because it will destroy the normal map orientation. It's not really recommended to create custom atlases from Megascans assets as they're not designed for this sort of purpose.

  You can load individual atlases into SpeedTree - this is how I've worked in the past.

  You'd have to make your own. In the example I linked, I used assets entirely found within the Megascans library.

  We're unable to provide specialized assistance with creating your own atlas maps. You can Google search this sort of thing - look up "texture padding" and you should get a bit of info to help here.

  For speedtree, I need to load Atlas maps that are not in Megascans, if, for example, I create textures based on Albedo, it will not turn out very beautifully because of the texture in png format or any other format, there will not be such a background as it is done in Megascans.

  I tried to apply the Opacity map with my settings, but this is not the result you need to get.

  Thanks Jonathan (Community Manager) for your answers

  If, for example, Megascans does not have the necessary assets, then where did you get the cards for plants?

  At the moment it looks like this for me, I will create more maps, but how to make the background so that the blending is more visually beautiful like Atlas in Megascans? Tell me another question, can I, apart from how to locally place my materials, models in the library?
