Me again. The build you sent me did fix the errors, but the rendering process is now terribly slow. I’ve tried both the 32 bit and 64 bit versions (my computer is 64 bit) and also completely removed both versions and reinstalled the 64 bit version again, but the rendering process is still extremely slow. I reinstalled then the old 2.65 version and the rendering process is now fast as it used to be.

weird!! Are you rendering with the same settings in both? using the exact same .rof file? What did you use? Raytrace with Fast Shadows? Path trace with direct illumination? Photon trace?

Yes, same settings in both – 100% size, raytrace, artificial lights and fast shadows and the exact same .rof file. In version 2.65 it took 39 seconds to get render view (first sample), while in version 3.0 in 40 seconds did only 7.8% (first sample) and it was slowing down.

ok! is it possible for you to PM me the .rof along with the .cfg (File / Save settings) and the texture folder? It's weird because the render engine did not change!

Is it any different to extrude before applying materials or the other way round, especially for glass material.
cause the interiors are looking really dark and transparency was set to 100

It doesn't matter. As long as your glass object has the glass material applied to both side, light can come in and rays from the inside can see out.

If you don't use an environment map, and only use the Sky for illumination, I suggest you use Path tracing and set the sky intensity to 1 or more.

Looking at your screenshot, I think you have your glass object painted only on one side.

ok I see the problem. You are using an image for the glass texture, and it's as dark as the frame. The render mix together the texture and the light, for example, your texture color = 0.1 and the transparency is 1, so 0.1 x 1.0 = 0.1, and 0.1 is only 10% transparent.

So edit the 2 glass textures you have and uncheck the image file assigned to them, and make the color of the glass white, then it'll look like glass. Here is a video of this...

BTW, nice design the house!

ok I got your model and the shower glass is set to 100% transparent white (Material = Shower Glass), but the inside glass material (the faces facing inwards) is 69% transparent and color is almost black (Material = Color_A25). Now, "Color_A25" is set to Refraction=Glass but "Shower Glass" is set to Refraction=None. So this is not working for glass as it keeps reflecting because of the dark color and that's why it's slow. in v3 you no longer need to worry about the glass face orientation, but in v2 you did.

So what I did is set "Color_A25" to white and set Refraction=Glass for "Shower Glass" and it renders at the same speed as in v2, and the shower glass now looks like glass.

When you make glass, it's always best to remove any materials from all the faces (front and back) but group the entire glass object and set the material to the group instead. The way you have it now is 2 materials for the shower glass, one for the front face and one for the back face, and only one of those material is set to Glass!

Another thing I may suggest, you can close off the bathroom (close all the walls) and use the XRay in Raylectron to render through the walls. If your wall has 2 layers, use XRay Level = 2. This way, you'll get true reflection off the mirrors as oppose to reflect empty space!

I followed your instructions and it works now at the same speed as before. Thank you for your help and for the suggestion about XRay.
