Creating a “beam of light” in Zbrush.

:b2: First you have to create an image in Zbrush, & save your “Document”.

:b2: Render the image, without any fog & export it.

:b2: Import the “Z” Image into Photoshop, or which ever image program your using.

:b2: Once you have the image in PhotoShop, you want to draw a selection in your image using the “Polygonal Lasso Tool”, in the shape of the beam of light for your image, using the image for a guide.

:b2: Create a new layer, over top of your image & make it the active layer.

:b2: Now you want to use the “Linear Gradient Tool” with a blend of “White to Black to White”, for filling the selection in the new layer.

:b2: If you set your “opacity” to about 50 or 60, you can see how the “beam of light” lines up with the image below.

:b2: Create a new layer over the image & below the “Beam of Light” layer, & fill it with “Black 0-0-0”.

:b2: Delete the original image layer, set the “opacity” back to 100, & Merge or Flatten the two remaining layers.

:b2: Now use the "Gaussian Blur"filter, set at about 20 pixels, to blur the edges of the beam of light.

:b2: Save the image as “Beam of light - Alpha”.

:b2: Open Zbrush & load the “Document” you saved earlier with your image in it.

:b2: Load the “Beam of light - Alpha” into the “Textures” of Zbrush.

:b2: Go into the “Render / Modifiers / Fog” window.

:b2: Select the square “Fog Alpha” & when it opens the textures window, choose the “Beam of light - alpha” you loaded earlier.

:b2: Set the “Intensity” to about 50 or 60, go to the “Fog Curves” window & bring BOTH points up to the top, so you have a straight horizontal line at the top of the window.

:b4: All you have to do now is to set the “Render Fog” button to on, & render your image in “Best Render” mode.

You can do the same thing with “Electricity” - “Smoke” - “Lightning”, there’s a lot that can be done with the “Alpha / Fog” in Zbrush. :smiley:

You should have something similar to the image below. If you have any problems or questions, please let me know. I hope everything works out fine & have a good one . . . :cool: Mark.

Kruzr, Your tutorial is brilliant. I just wanted to reach out from my virtual dungeon and say that sometimes I’m too lazy to go into photoshop from ZBrush. Upham had started an idea about using a stencil of a MRGBGrabbed cone shape. I used this idea after baking my rendered image, and then using the shading enhancer tool through the cone shaped stencil.

Your tutorial along with Upham’s posting inspired me to be able to do this. Thanks guys :smiley:

Very nice idea, also nice image! :wink:

I’ll have to give this one a try. Thanks & have a good one . . . :cool: Mark.

PS: ( You’d better find a way to get some SUN on your hand, your skin is starting to pick up the texture from the wall. Heheheh. )
