Hi All,
First, let me just say thanks for making SweetHome3D. Compared to the old days when I used radiance it's a much nicer way to lay things out! No more having to figure out thousands of coordinates for every point in my head. I want to talk a little bit about some of the challenges I'm facing too in case any of you guys have ideas.
1) I really want to be able to control specular and diffuse reflections independently for every texture (and override at the material and furniture level). The countertop is a good example of this. I want diffuse reflection for the cabinets and brushed metal, but specular reflection for the quartz. I may even want a combination of both for some surfaces like the floor. My current thought is to maybe put a thin layer of glass as a veneer (see the coffee table, glass must have a special specular property?). This isn't really ideal though. Would it be possible to modify the code to associate a shader (or multiple shaders) with different textures?
BRDF (and BSSRDF!) control would be really cool too, but one thing at a time. ;)
2) The original images came out very under-exposed. I was able to clean this up with levels in the gimp, but it would be much better to get the .hdr file and be able to really adjust the exposure properly. After looking at sunflow a bit it looks like this theoretically is possible, though with how SweetHome3D interacts with sunflow it might be some work to expose.
3) For some reason surfaces that have a transparent png texture are rendering black with the path engine. Not sure what's going on since they render fine onscreen and (I think) normal engine. Maybe a problem with sunflow?
Thanks again for making SweetHome3D. It's making the process of remodeling the kitchen with my wife much smoother. :D
