Materiality doesn't keep while rendering to Sketchup Diffusion. Please, why?

Why doesn’t the materials keep the same while rendering to Sketchup Diffusion from the Sketchup model?

It is a known thing, and more material fidelity might be added in a later version. Note that Diffusion is not a rendering plugin but an AI tool that builds an image based on your prompt, your SU screen and the image material it has been “trained” with.

In the prompt, try to add the materials you would like. “modern house with wood panel walls, vibrant tile floor, and white ceilings.” And keep trying, it’s not exact, and the best options may come with the 3rd or 4th try.
