Redshift users, post your tips tricks here please!

Recommended Posts

Ok, so not a whole lot of Houdini Love over on the Redshift forums. Mostly Maya, 3dmax, C4D (in that order)

https://www.redshift3d.com/forums/viewthread/10860/

 

Hence the reason for my posting here.

Anyone care to share any Redshift tips, tricks and tutorials specific to Houdini users?

 

Here is one great tip that Adrian from Redshift  was kind enough to share for customizing RS Spot lights

Here is a Python script I wrote, Images As Planes, that reads in images in a folder and creates Redshift Materials with texture maps for each image in the folder. If you are looking into creating materials for Redshift, via python, consider this example code.

 

Here is a procedural planet rendered in Redshift. It routes VEX/VOP generated noise attributes to Redshift materials.

Create a Redshift SpotLight, unlock the HDA and then use the Jump button to jump into the Redshift light shader. From there you can connect a rsTexture to the color input of the light to project an image as the light.(i.e. light gobo)

If you enable Volumetric on the Redshift ROP and set the Volume Contribution value for the Spotlight greater than 0, you get a volumetric light.

Here is a Redshift instancing ground cover setup. The meshes included come from cc0 sources. This mesh set contains grass and spring time plants but the system can scatter any mesh set across the target surface. (i.e. rocks, trees, plants etc...)

This scene uses the image based volumetric spotlight to achieve colorization.Untitled-1.jpg

I have been working with rendering volumes in Redshift. As I render more objects as volumes I kept coming back to this one setup. I thought I'd post a screen shot.

Here is a blood cell flowing inside a blood vessel. The cells move along a path to form the blood stream. The blood vessel itself is also generated from the path.

Yeah, sometimes I like to watch paint dry too.:huh: (especially when I'm paid by the hour)

Here is an example scene that demonstrates lighting with only material emission. There are no lights in this scene. The shader uses a RaySwitch to decouple material based emission from incandescent emission. This allows you to overdrive incandescent output while not blowing out your diffuse. You can even choose an alternate color for the incandescent light as shown in this scene. The sphere emits RED but the incandescent emits BLUE.
