Trapcode Particles accept light
Hey folks,
i am a newbie and already found some good adviceover here. But right now i need you help.
I am using trapcode 2 and i made some smoke particles. I just want to make them to only appear when my light source is shining on them. but i don’t find the material optins with “accept light”. is it possible to do this with trapcode v2??
Thx for your advice

Place the particles under the light source and change the particle layer’s track matte to luma matte. You may need to fudge this a bit if you are using actual 3D lights in AE, by pre-comping them, or using trapcode lux.

thx for your help.
i tried it and it works for a title but the somke particles are always bright. i tried to do the light like in this tutorial with a light source, a white square, a radial fast blur and a null object point: https://www.videocopilot.net/tutorials/advanced_3d_light_rays/
is there anything wrong? i am trying to fix this for about 10 hours right now but i think i am too stupid :/ -
it seems that any layer blocks the light, even adjustment layers don’t allow to pass any light

If you can save the project back to CS6, you could upload it and I would take a look. Otherwise if you could post a screen grab of your timeline, with the track matte panel onscreen, and what effects you have on layers showing that would be helpful.

oh yes it would be very nice and helpfull if you could check the project… i am doing many tutorials right now and learnign more about after effect but now is helping out with this problem….
thx so much 😀

I precomped your light source, then used that as a luma matte for your particle layers, I think that was what you were trying to achieve.

is the same possible for the text layer? if i try it with the luma mask and all settings like the particles it disappears.
how can i take revenge?
