Is there a way to have the multi shader converted to individual shaders?
For some reason the shader jumps during rendering with octane.

Hi Shadowgin,

Sorry to read that you run into trouble. Perhaps the support has an idea, but I’m not certain if not the support of the Octane Render would be the first address to check.

You might try anyway
http://www.maxon.net/support/support-questions.html

The Multi-Shader is “triggered” by several ways of information. (Not that I have any evidence that the following makes sense, nor do I believe to solve it here…) Have you tried to use only the Indexed base “Mode” for the distribution?

To be on the save side, I would just use at least the MoGraph Cache.

However, what do you want to achieve? To ask a general question is most of the time more difficult to answer. Sometimes a specific case can be solved with a different procedural.

To answer the question, I’m not aware of any option to set the Multi Shader from its function to single clone shaders.

As usual, perhaps a scene file—reduced to the bare minimum that can reproduce the problem. But again, I have no running Octane Render here, based on not have the right CPU, etc.—so no Octane support.

All the best

Hi Dr. Sassi

So the work around I thought of was to figure out a way that I can take the colors and make individual textures from. I would use these individual textures and apply them to each object based on their index to match what mograph is doing. I’m assuming in expresso.

I attached a small c4d file. It’s not the one at work but if there is a way to do this work around then it would solve the glitch or I have a new tool to work with.

Thanks Dr. Sassi
I hope that’s more detailed.

Thanks for the scene, Shadowgin.

If I get this scene correctly, as it stands for your target, the colors are not so much following any animation nor structure, it is pure random.

I see as well no Multi Shader. What would be inside of these “layers”, just color or images? You mentioned it, but its not in the scene file.

Just to explore, and hopefully do not wast too much of your time—is the attached scene rendering in your Octane set up?

All the best

P.S.: I hope this one minute clip works for you.

I have attached the scene file, so you can test this with your set up directly. I guess that rendering from a movie as “Texture” is possible with Octane.

My best wishes

You can download the file and the movie for your testing.

I have sped up the clip, but it is doable in a few minutes, seriously.

Hi Dr Sassi

That is odd.
I’ve attached a screen shot so you can see what is going on.
Nothing special in this scene. I’m just trying to figure out a way
to be able to place the same color on the same one the multishader has.
I basically have a city scape done but if I can figure out how to do that
on a simple scene then it should work on the larger one.

I can’t see a screen shot in post #5. [800x600 max]— Edit: Thanks—now I can see. So the attached file should work, but for Octane you must do a test.

Yes, I used for my short feature JET the MG Color Shader to get variations in my 4,000+ buildings in one scene. Looked good on the big screens during the festival circuit.

If you only like to have the color, set the objects under a cloner and apply the Random with your color settings. Apply to each child of the Cloner a MoGraph Color Shader. Then select the Cloner and press the c key.

The clones stay in place. I used two Random Effectors, one for position and one for color based on different Min/Max values.

Scene is attached.

Have you checked the one minute clip in post #4? ;o)

Here is your file back.

=====

I selected the Fracture Object after deleting the Texture Tag.

Then I pressed with the active Fracture Object the C key.

A material with the MoGraph Color Shader is needed (not Layer)

I selected all 64 clones—well—child objects now.

With new material selected—I used the Material Manager>Function>Apply

Render.

Done. :o)

Test the result in Octane, please, and report—so others will know. Thanks.

Alternative:

Camera Mapping. :o)

If you camera moves, find two positions if needed to render out the start and end frame of that move, render perhaps twice in “resolution”.

Project one and then the other, it might need an alpha channel in one to combine both. Depends on the camera-move/parallax.

It can even catch all light and shadow, perhaps accelerate the rendering even more.

My best wishes for the project.

The link contains your file, converted to camera-mapping. In this way, even the light is “baked” already. It should be possible to be rendered easily—even with any third party render.

(I have made a lot of camera-mapping tutorials (here and in the link below)

Hi Dr Sassi

Thank you again for all your help. We figured out what the problem is. We had an animated cube in the fracture object that starts at the frame where the problem starts.
After taking the keyframes off the problem stopped. I did learn some tips from you with this question though. That may come in handy in the future. Mapping the textures
using xpresso is similar to the baking process I tried with mograph. It made me realize that I was on the right track. I will keep your other tips in mind as well.

Thanks again as always

You’re very welcome, Shadowgin! :o)

Thanks for the nice feedback!

ENJOY!
