If my idea works, yes, that’s exactly what I had in mind! (Clearly it’s a Dome with the HDRi applied, so you will notice the “deformation” when you go far from the center, however the distance you can go far has been limited to make the deformation almost imperceptible, just as I thought it would work if I can do it as I’m thinking about).
But, better, you can wait until I confirm that I have achieved it before buying! I have made a fast test right now and I think I have achieved it, however it will need more tests to ensure that it works properly, maybe during next week. Please, could you explain me how can I test it by myself in an external software? Do you know if that software will respect material “attributes” of the Unreal material, or will it only take the maps and anything more like node’s multipliers, UVs offset, etc? Or won’t it import the Unreal material and you are talking about firstly importing the mesh and then creating and applying a new material, all inside that external software but simply applying only the texture exported from Unreal?
Thank you and regards!
