Tutorial: Offsetting Texture Scale Using Vertex Painting

bgoodsell

Hey guys. I wrote up a tutorial on a shader I wrote over the weekend. Using a single vertex color, I found a way to paint various shades to set the scale of a texture. It's helped me modulate parts of my ground texture, so hopefully it will be use to someone else.

Check it out HERE.

You're fucking ACE man! I wasn't able to figure out how to marry the Range Checks at the final part, thank you very much for this!

Can this be pronged with a full set of Vertex Blend on the RGB? Or it it only limited to one channel?

Again, THANK YOU SOO FUCKING BLOODY MUCH! If we ever meet, Beer is on me.

@Ace angel:I think your limited to 2 color channels max. You could duplicate the chain and be able to control U and V independently. I don't think using the Full RGB channel would have an advantage over using one specific channel since we're just looking for a gray scale range.

Very cool man! Great use of vert blending.
