Hi,

I'm looking for a way to apply multiple tiling textures with adjustable scale/ratio to a normal model, which is going to be the base architecture for my level. I also want these textures to blend smoothly and on top of that, I want to apply a pre-baked lightmap later on.

I figured the best solution for my problem would be to use mtl_terraintex as material, even though I'm not using a terrain at all, as this FFP offers everything I want - but it sadly has absolutely no effect.

I've set up the skin textures as described in the manual and all I got was this:



Now, as I barely have any idea of shader programming, I would like to ask you to help me out. Any ideas (or even full code examples ) appreciated!

Uhm ... what?

What did you do in order to achieve the screenshot?

This should give you a good start:

Just wanted to suggest triplanar texturemapping but Superku was faster

I guess using this is the best solution (if you are able to use shaders).

I thought it was obvious, but perhaps I should go more into the details here. I created the model (1a) and unwrapped it afterwards (1b). Then, I painted the alpha mask for the second texture (2d) directly onto the model's surface.

I imported the model using MED and assigned the first texture (2a) with completely opaque alpha (2b, in a 32-bit TGA, if that matters) to skin1 and another texture (2c), that I wanted to blend over the first one, to skin2. The latter has the previously prepared alpha channel.

I saved all that stuff as MDL, loaded it up into WED, assigned mtl_terraintex as material, built the WMB, started my project and made the screenshot.

Now I guess you wanted to imply that I'm completely nuts, but let me explain my theory: when I have an HMP file, it still has the usual UV mapping as any other model. The textures assigned to its various skins are nothing more but images with visibility information for the UV coordinates. So I thought, what works for heightmaps should very well work for models, too (which prove wrong, as you can tell by my initial post).



Thanks @Superku and Kartoffel. This technique does indeed look very helpful. I'll have a look into that, though I doubt I'll be able to make use of it. I'll just post again as soon as I encounter problems.

No. I just wouldn't have come to that idea.
Unfortunately this is not the case AFAIK. That's why mtl_terraintex3 won't work for models. But why did you use a model when you wanted a terrain in the first place?

The shader I once posted (the one Superku posted the link) is like a better version of a terrain-texturing shader.
It just doesn't support mutliple textures. (but this can be changed)

Okay, I think I got you wrong then. Nevermind! ^^


I think you nailed the problem here. The reason why I'm using models instead of terrain is that I need very organic shapes for my level architecture. See, I'm working on a sidescroller (imagine something like The Cave), and working with terrains and blocks is sort of outta question, because I need to be very flexible and stuff.

Anyway, I got that shader Superku and Kartoffel were pointing me to working so far and I also somehow managed to implement three different textures for different slope angles. I think that will create roughly the same effect I was trying to achieve with the aforementioned method. Thanks!
