Texturing in Max

[Devlin2013]

Hey,

I was wondering if anybody could answer a question for me. I'm trying to learn how to do good textures in max and photoshop. Right now here is what I do. I select my model, apply a sub-material texture. Select all polygons, and apply sub-material. Mesh select. UVW Map, fix with box or planar (I'm trying to texture a building right now) then UVW Unwrap. I set the unwrap to box so that it shows me all sides. I save the screen and import it into photoshop where I make my textures according to the unwrap. My problem is that when I save the picture for texture, it fills in all surrounding sides with a pure white background, which in turn shows up on the model when I try to apply the texture. How do I make all sides of my model (ie. doorways, windows, ledges, etc) accept the texture I made for them and how do I get rid of the white?

Then, how do I do the same for rounded edges, like on a car or space ship? Anybody who can help, or direct me to a website that not only tells how to texture but explain the tools and methods as well, would be greatly apprecitiated. Thanks.

When you have applied the UVW Unwrap modifier there is an edit option. I suspect what has happened is that all the faces are on top of each other and are having the whole of the map applied to each face. When you select edit, you can select individual faces and move them around in the texture space. Then you have the option to render out the UV coordinates to an image file which you can paint on top of

Here is a screen shot of an unwrap I've done, a picture of a texture I've made (not for the unwrap building, but just to show the white background) and a picture of a texture made by....I forget his name, but he made the tutorial "Making of Urban."

This is how I've been setting up the unwrap. I don't think they're stacked on top of each other but I don't know since I don't yet understand the method behind texturing.

Thanks for the tutorial. It actually answers a lot of questions I have about multi pass compositing and bump mapping. Do you know why my texures are surrounded by white? Am I not setting up my unwrap right? (I assume so, since it's not working) and what about the car texture I showed you, it looks like he set his up the same way and the final render completely covers the car with not interference. I don't get it and I'm really frustrated, I've been trying for 3 weeks to figure it out myself.

Perhaps post your painted texture map. You need to paint on top of where the green lines are in your unwrap. Provided every green line is within the non-white part of your map then you will not see the white parts on the building. A screenshot of the building with the texture applied would help to show what's going on too. A render will do

Actually, another trick is to create an image with a white and light grey checker pattern that is the same size as your actual texture map. Add some random text on top of the checker and apply that image to the texture. You can then see if some of the polys were unwrapped upsidedown or back-to-front

Thank you both very much. I'm going to try that new method tonight and I will get some pictures of my render and post them tomorrow. Thanks again.

If you are still stuck tomorrow I probably won't be around to help, but I'm off work on Friday so I might be able to sling together a quick tutorial if you still need it. With luck you will fix it yourself though

A quick tutorial would be great. I still haven't figured out the problem yet. I'll be sending those other pictures today when I get home from work. Thanks again.
