I have a question about Steempipe's terrain multitexturing effect -

Is there any way to use detailmaps in conjunction with his shader? Like, for one of the tileable textures, have a smaller detail map, and then for the other, have a different detail map? I was playing Halo yesterday and I noticed that it looks like they did this. There are 2 terrain textures and both of the textures has its own detailmap, and it looked really good.

Thanks for any help.

P.S. Let's see if anyone can reply before I finish my homework! Only 10 more vocab words!

Yes... possible... My current FFP effect has a unique detailmap for each texture. It still needs some cleaning up though, as I have had to abandon it.

Thanks Steempipe, this isn't the effect thats currently on your Terrain page on your site, is it?

No.. it's not. That one is way outdated. I really need to get the website updated one of these days.

Since I need to incorporate the effect into a current project, it needs to be cleaned up very, very, very soon.

I'll send it to you when I've got it under control and you can help test it. I would say that it will be ready by the 12th of Oct, hopefully sooner.

OK thanks for the help, Steempipe! I really appreciate all you are doing for the community as far as shaders, terrains and such. Just thought you should know that.

Cool. Thanks for saying that.

Would I be able to do some testing of you new shader as well? I couldnt convert your old one completely to directx 9, just the FFP part of it... it seems to run a bit slower than the pixelshader/vertexshader version of it. I cant seem to convert the pixelshader version of it right. Also, while I got the FFP version of it working right I cant seem to get the textures to change there uvscale independantly. Hope your new shader will be able to do this stuff - Thanks, I also appreciate all the hard work your putting into progressing shaders in 3DGS!!

BTW - Steempipes FFP shader edited slightly to work with DX9

After I work on getting multiple detailmaps in this thing, then my DX 9 FFP terrain effect should be ready to test. Hope it will work soon...

@LoganTheHogan & William: I'll send you a link when it is ready to test.

Thanks, looks nice.

Good news LoganTheHogan & William, we are getting closer to a desirable DX9 FFP Multitex effect.

Not running too bad, about the same as my pixelshader version with as many textues. Tweaking and optimizing is the next step.

The colormap is just a basic big skin stretched across the land... but when all done we will be able to apply tileable textures in it's place.

Here are (3) Detailmaps applied, based on blendmaps



And here is showing that lighting is working across all blends. finally.



Soon I will be notifying you of code downloads.
