Making terrain Using Grey scale maps

[cs00bren]

I'm trying to make terrain from a grey-scale Tif. i got this tutorial for it but i can't get it to work. the main problem is i can't find TEXTURE SOP has it been replaced in Houdini 5.5 any help would be very usefull.

1. In the compositor, load the height data image into a FILE COP.

2. In the sop editor, start with a GRID SOP, makes rows & columns 20,20 (say)

3. Append a TEXTURE SOP to the GRID SOP, no parm changes needed.

4. Append a POINT SOP to the TEXTURE SOP, and then you'll need

to enter this nifty expression to replace the $TZ value in the POINT SOP. To help work this expression out, hit ALT+T - you should get the text window to pop up. At that prompt type in: "exhelp pic". You should see this:

float pic (string copname, float U, float V, float color_type)

and a description of how to use it (ignore the picni() ).

So, in the POINT SOP's $TZ enter this:

pic("/comp/file1", $MAPU, $MAPV, D_CLUM)

I think it's been renamed to UVTexture.

Cheers it has been renamed to that.

i finally got it to work with the changed equation of:

pic("/img/img1/file1", $MAPU, $MAPW, D_CLUM)

it works just fine now all you do is change the greyscale map and surprise surprise it changes the landscape in houdini.

You can also set HOUDINI_COPTOPMAT variable(as yor system variable or withing Houdini) and this will enable the good, old textures and materials

They will be completely gone in Houdini6!

Hi there,

I took a small moment to build a SOP from VOPs to do your heightfield thing. Take a quick look at the setup - in particular the VOPs. Note you still need a grid with texture coordinates for this one. Everything is in the attached hipfile.

Enjoy!
