using spotlight disables rgb

ZBrush Usage Questions
#1

Hi,

I am having a problem with polypainting using spotlight; as soon as i load a spotlight texture (everything looks fine) i am not able to paint a model anymore. this means if i leave spotlight i am also not able to do “normal” polypainting.

when i close zbrush and reopen the tool again, i still can´t even polypaint using the standard brush (with rgb of course) nor polypainting using spotlight…

this already happened in zbrush 4r2, i hoped it would be working with r3, but unfortunately it doesn´t…

i didn´t find a solution to this problem anywhere around zbrush central…:confused:small_orange_diamond:question:

plz help!

thanks michael

edit: now i tried to unwrap UV´s using UVplugin; but i can´t even polypaint the “protect” and “attract” areas since polypaint isn´t even working on the cloned mesh anymore…

hmm sound s like a new bug. If it is, we need a fix pronto. :o

Spotlight and polypainting works fine for me in 4r3. It worked fine in 4r2 and 4r2b as well. As long as you have RGB turned on and the intensity at 100 it should work…

i know that it should work… but it doesn´t.

#5

What brush are you using (the move brush doesn’t work as a polypaint brush)?
Have you tried using different textures in spotlight?
Can you record a screen capture of your steps?

hi,

i have created a recording (colorize on, no masking, rgb on, standard brush, intensity 100%, color red…); i didn´t find a way to slow it down …

i also put the tool in the zip folder; to explain: i can polypaint other geometry, but i cannot polypaint this tool

here is the link:
http://www.storage.maehring.at/TEMP/120302_ZBrush4r3_polypaint_issue.zip

when i export the geometry as an obj, switch to simple brush and the reimport the obj i am now able to paint it (but have lost the color information that was painted so far).

in the case of this model it doesn´t really matter; the problem ist, if this happens further down the road… then you would have to bake the polypaint into a texture, then export the geometry, create a new tool, apply the polypaint using the texture; this leads to a loss of information of course.

thanks for your replies,

michael

Ah, I should have known. As soon as you said texture map I know what your problem is, I don’t even need to load your tool. You can not and never could polypaint when you have a texture selected under Tool > texture Map. The texture map overrides any polypaint color and will no longer display polypaint info when a texture is displayed.

If you want to bake your polypaint to a texture and then export your mesh and re import it and then continue working on the texture. All you have to do is load the texture into your tool and run a tool > polypaint > polypaint from texture. That will re apply polypaint onto your model from any texture, then you can continue polypainting.

Also, if you have a texture in Tool > Texture map, you can paint directly to the texture using Projection Master.

thanks, that did the trick!

even if the “texture on” button is disabled, polypainting is disabled (if there is a texture selected)
