Rocks by using displacement and color maps made with Photoshop.

Cool again! I've used a blocky gif file a few times for displacement of my blocks. Actually I don't know what would be faster to render/compute; an image file, such as these, or a huge set of blue nodes such as Jon's blocky ones.

Fantastic! Great information. Thanks, René.

Very nice.
How did u applied these maps in TG to get that result?

An image file is certainly faster! Why? I don't know; maybe because, apart from the displacement, the texture already exists and less rendering is needed. It also requires only one displacement (the gray value of the texture) as opposed to a lot of procedural textures.

The textures are TIFF files loaded as an image map and mapped along side Z or side X. Unfortunately this only works in one direction, and the other direction gets stretched. So the camera has to be in exactly the right place. Important: the image maps must be passed through a transform shader with world space enabled.

Thank you. Very interesting. Will try it.

Really interesting technique beautifully executed.

I used a Y projection (with my squares.gif) and merged that with a transform shader with 90º rotations, which also works.

It didn't occur to me that I could do that with image maps. I'm going to try it. Thanks for the tip!

I've done cliff faces like that in the past as well with Y projection

Very impressive, René! Have to give this a try.

Were the texture files entirely hand-painted in Photoshop? Looks like some filters may have been applied to break up the colors and patterns.

[René]

The displacement map is initially hand painted. Next I used filters and levels to add extra detail. From the displacement map I extracted the color map on which I applied a number of other operations. From the color map I generated a bump map on which I painted extra cracks and irregularities.
It has been a constant going back and forth between Photoshop and Terragen.

Great stuff!

Beautiful !
It's a great technique, i'll give it a try ! Thanx for sharing !
