I have run into a few problems when it comes to displaying custom textures inside SoftPlan, especially with darker materials using Ray Traced Mode. Here are the textures as a reference to show how darker textures are not displaying the same as lighter ones when rendering.
Here are the textures represented in the space under the same lighting conditions. Swapping the texture locations does not change the overall results of the texture brightness/shading:
Here is the space rendered in Textured Mode with the SoftPlan thread recommended settings. Notice how the darker tile is more closely resembled to the original source texture, however Ray Traced mode does offer higher quality rendering but doesn't seem to work well with these darker textures.

Here is the same space rendered in Ray Traced Mode with the SoftPlan thread recommended settings. The darker tile texture is almost completely dark with little visual representation of the texture pattern. I have adjusted all the settings including increasing roughness to make the texture brighter (in this example roughness is at 100%), decreasing metalness (in this example the metalness is at zero), and I changed uniform to 100% but that barely brightens the texture and is still extremey far off from the original.

I have tried adding additional lights in the space such as area lights and atmospheric lights, but it does not aid in getting the texture to represent like the source material. This is more so an issue with darker textures since you can clearly see that the brighter brown tile looks almost the same to the source texture with very minimal saturation changes in either rendering mode. I do not know if this a development issue since I have noticed other users having lighting problems with exteriors being too dark in Ray Traced Mode and I also have experienced this myself where the exterior is significantly darker when rendered in Ray Trace Mode compared to Textured. Because of this, I am doing most of my exterior shots in Textured Mode and interiors in Ray Traced but this issue has me in a stand hold since the client is wanting to use these darker materials, but I can't represent them in 3D without it fading almost to black.
