Hello salvuzzo. When you say "i cannot visualize the model with his texture, but jus as meseh surface, is it normal?" Do you mean that you only see the model as a "wirefame"? In general I find it quicker to navigate around my models in Kerkythea using the wireframe view, but sometimes I have to check the model to see where the heck I am. To view the model as "shaded with textures"(KT calls it "solid rendering"), Go to VIEW> ADJUST> and choose "SOLID RENDERING"(your other choices are Point Cloud Rendering,Wireframe Rendering,Mixed Rendering and Hidden Line Removal. I believe all of these have to do with your "screen view" or how you see the model BEFORE your finished render). This should change the screen view to solid view of your model... I find this screen view slows down KT alot for for me on my old Mac. Too bad KT does not have "Shaded" or just "Monochrome" views as choices. I usually use KT for quick renders(I'm still trying to figure out all the awesome lighting features,HDRI and rendering choices),but the neat thing I found is that when KT opens up the model, it uses the last view you had in SU when you exported it. I usually set up my camera view in SketchUp before I export my model since I find it and more intuitive to move around in SU than KT. By the way if you are thinking of adding lights to your model, it is best to do so in SU and not in KT(at least at first). It is really cool how the "point lights" snap to a surface(I wish some of my other 3D programs could do that). If you add the lights, this will disable the "SUN" in KT by default... so if your lights are not bright enough you might see the scene as being too dim. Just keep experimenting until you find the right intensity for your scene. Good luck!
