Particle Custom properities
-
Hello
I am studiying on particles and I did update my cinema a minute ago but after this my particles are not givin response as I expected. Maybe I am doing someting wrong I dont know. Node modifier is ok, it shows me the texture that ı put on it but when I add the material on particle it shows me black. what is the reason for that
Thanks

Hi anywhere-final,
Thanks for the file
I have run the project in 2025.1.2
then in 2025.1.3.
When I compare both (A/B Picture Viewer), I get this:
No difference
If you experience a difference, then tech-support should look into it.

Fingers crossed that can be solved quickly.
My best wishes

interesting Did you check my material setup ? in the render , yes we can see but on the material side it shows us only black. Without particle modifier, it should show material also am I wrong ?

Hi anywhere-final,
In 2025.1.2. In comparison to 2025.1.3, both give me the image during render time when the Material Tag is on the Particle Group.
What is the Redshift Asset Manager telling you?
All the best

I want to show but I cannot share any picture here
-
it says always dimensions is very big... what is the limitation here for sharing simple screenshoot ?
-
The image can be 500 pixels high, but wider, anywhere-final; I know it is small.
If you need a larger one, please use one of the following: Dropbox, Wetransfer, Google, Adobe, or Apple cloud services. For security reasons, that is the current selection. Thank you.
Cheers

Hi again
https://ibb.co/4RC4bQ1H
https://ibb.co/tMYNVkX6
here there are two pictures . One is without material one is with material. But I think material version also must show mat. But it is only black now. I think I did true "get custom property " from user vector data but it looks not work for now.
Maybe ı am doing something wrong any idea ? -
Hi anywhere-final,
Sorry that you did the extra work with images. I would always take your word for it that the particles stay black. Images might show that, but what else can I gain from it? Project files are the key to solving problems, as long as they are not based on hardware or configurations that I can't replicate.
I hope I can find the problem, as it may help others.When I turn off the Project settings>Simulation> Particle Custom Properties, here is the setup for the "UV" channel, and then I get white for the Particles, not black. Is the channel set to Vector? (Wild guess)
If I mess with the Path of the image, it doesn't go black either.
Is the texture showing up on an object? I just want to check if it is available.Since I can't reproduce this with the file you sent initially, I guess that it is perhaps a tech support case:
https://www.maxon.net/en/support-centerIf you can share the project (for security reasons, I will check only Dropbox, Wetransfer, Google, Adobe, or Apple, no zip/rar, and no tiny URL, the URL pasted into the text directly, no HTML. Images are also available, but please only use these cloud services, as those check the items.) Thank you.
Please save with Assets. Thank you.
Enjoy your weekend

Hi!
I am having a very similar issue. Followed along with Mr.Noseman from this tutorial.[https://www.youtube.com/watch?v=SeYP8oJUDTQ]
Couldn't get my rebuild to work so i grabbed his example files.
The setup works on my personal machine which is using Redshift 2025.2.0 but it fails on my office machine which is using Redshift 2025.3.0
My office machine only outputs black specular spheres.Bonus weirdness: using Optimized Sphere in the Redshift Render tag, as used in the tutorial, provided no color channel information in the render, only a black specular ball shows up. Using Sphere Instances in the Redshift Render Tag gives me the image i want, but it is mapped ON EACH individual particle/sphere instead of OVER the whole field of particles. I include this to say I don't think it has to do with file linkage, at least not completely.
Here is a link to Noseman's files:
https://maxonvfx.com/4i6CygTi am looking for an alternative method to inherit/transfer an object's color to the particles emitted from it from the same UVW location. I like how Noseman's works, just wish it worked on the latest versions of Redshift or c4d so any pointers or insight will help me understand the whole system better.
Best,

Hi Loren,
Please for new questions, a new thread. Otherwise the forum is less useful and harder to read, or search, thank you.
I assume you refer to the file "Custom UV and Position Back & Forth 01A.c4d."
Color and UV are available, but no offset or other changeable data is working. I have filed a report.
I have written a note to Noseman about it.
Please allow time until it is morning here on the West Coast. Thank you.Anyway, there is a different way, and I use it with a Standard material (to set it up go for a moment into the Standard Render Mode, call up a material, and place the image in a channel. Please compare the file below.
Then go back to Redshift. This color channel can be used inside the Vertex Color Tag/map, which means the mesh needs a very good density to produce enough "points."
This map is needed inside the Surface Emitter in the Properties, Color Map>Vertex map.
Then, use a Surface Emitter and receive color for the particles. I have used an RS Render Tag here.
Please let me know if that works for you.
Cheers

Heard and heard. It works just as I need. Thank you for such a clean fix!

Thank you very much, Loren, for the reply.
I'm glad it works for your project.
Cheers
