Hi!

I really like Wood Workshop so far... I've used it for what... 2 hours now /tongueNew members can't link' class='bbc_emoticon' alt=';)' />
The one feature I'd like to have in it is the posibility to render out a separate bump-map for use in my 3D package. This way the textures would hold up better with changing lighting conditions.

Not sure how you may do this for what ever program your using, but it's easy in Terragen. Just turn the texture to gray scale with a photo editor. Then I use terraformer to change it to a .ter hieght map. But so far I haven't gotten anything exceptable. Generally I have to darken the bit map quite a bit to keep from haveing spikes. But I'm still experamenting.

Yeah, you could just pipe the grayscale value of an image into the bumpmap channel in just about any 3D-app. But, while this would be acceptable in many "unstructured" woods and stone surfaces it would be quite useless in any texture that's more structured where you recognice the bumped elements (E.g. textures featuring tiles.)

We will be looking at implementing this type of thing in the future.

on the same topic - generating a normal map ( rather than a regular bumpmap).

btw - this program rocks - and it's nice that it's free. /biggrinNew members can't link' class='bbc_emoticon' alt=';)' />

Fantastic!

Currently, am using this method to make normal maps......

I wouldn't count on normal maps showing up in Genetica /smileNew members can't link' class='bbc_emoticon' alt=':)' />

Ultimately a normal map is meant to display 3d information - you take a low polygon-count model, apply your normal map, and voila, you get something that LOOKs a lot higher-poly.

Making low poly look high poly is the reason for normal maps! It's a technology geared towards real-time rendering (ie, games), rather than high-resolution rendering. And it's not like you can 'paint' a normal map either.. it's generated from a high poly model onto a low poly model. Very dependant on the geometry.

..... Normal maps can be generated the same way height maps can. you dont need a high poly and low poly model \:

There's buckets of ways to generate normal maps, including converting bump maps, one of my favourite methods is this: [url="http://66.70.170.53/Ryan/nrmphoto/nrmphoto.html"]http://66.70.170.53/Ryan/nrmphoto/nrmphoto.html[/url] /ph34rNew members can't link' class='bbc_emoticon' alt=':)' />

lol.. nice. I saw a tutorial to do exactly that in 3dsMax...
