I don't really sculpt, but I can answer several of your questions:

The high poly model is only for baking light maps, normal maps, etc. The actual model used in-game is the low poly version which usually have tri limits of 200-1000 or something. The high poly sculpts that people make have hundreds of thousands (if not, millions) of tris so these are definitely not viable for use in-game where real-time rendering takes place.

If I were you, I'd pick up sculpting if you want to do dota modeling. It's more necessary for Dota whereas in TF2 you can get away with low poly modeling the entire way through. I'm not really a professional or anything, so I can't really recommend what type of program to use for sculpting, but I do know of three good ones: Mudbox, z-Brush, and 3D Coat.

And the rendering of the maps can be done externally or within those programs. I think Lenny/Vlad might have some tutorials regarding the whole map-baking process.

Thank you very much for answering! Yes, i think you are right about the sculpting part. I'm kinda new to zbrush, but i have some experience with Blender, so i'll try to use both programs and see what can i achieve. Again, thanks a lot! :)

You can add a dummy material for that purpose. Create a new material, go to the transparency section, check raytrace, and use a low alpha value, like 0.3 or 0.5. Then go to the object data tab, look for the display section, and check transparency on.

Don't forget to erase the dummy material when you finish your modelling, or check the "ignore blender materials" in the smd exporter addon when you are about to export your model. GL.

Ok, i know that you had this problem some weeks ago, but still: If you want to create a new uv island from a bigger one, you can select the vertices and press the Y key, for spliting. That way, you are separating those uvfaces from the rest of the island, and you can scale, rotate, or move them separately.

Hi guys! After some months of hard learning i'm back to modelling for DotA 2 again, but i still have my doubts about the LODs. I saw that a lot of people creates a base mesh, and import it into zbrush or mudbox for sculpting it, but what i don't know is if the sculpted mesh is exported for using it as the Highpoly, or you just use it for baking the maps you need. Another thing that troubles me if both Higpoly and Lowpoly need to be unwrapped using the same texture. Finally, i have a question for you guys: Should i bake my normal maps using the Blender Engine or a 3rd party software like xnormal? Thanks for reading this far! :)

Haha, it's ok Helljumper, thanks a lot anyway. Your tutorials have already helped me a lot :)

Hey guys, i'm kinda new to modelling, but i have a LOT of questions. So here is only one of them. Can i attach particles effects to any item in dota 2? or only to certain heroes items like anti-mage? Tanks for reading this far!
