Adobe Substance 3D Stager categorizes things well, sorting them by model, material, lighting, and image. When you choose materials, it’s neatly classified by name below, such as wood, cement, etc. Twinmotion, on the other hand, requires multiple clicks to navigate and search. If you need a second material, you have to go back to the root and start searching all over again. It’s a peculiar design.
The second suggestion is: incorporate terrain editing and erosion tools. The grass brushing feature is already available, and it can be directly adapted from UE for simple sculpting.
The third suggestion is regarding urban filling; if AI can identify what object it is, simply applying a material would suffice, or adding surface structure grime, etc., in the form of decals. As a scene building tool dedicated to UE (Unreal Engine).
I believe that you can surely outperform your competitors
