Hi there,

thank you to Varomix for this space... I'm relative new in Houdini and in this time I'm working a lot on decostruction, PyroFX and much more. I have a bit question and for this I open one topic for do all in one time (and I have in WIP because I want take all information for create more rnd and test).

- How can I use the matte for capture only the light on it?

- What the best way for create the explosion of RBD? (use the rbd object or another way)?

Thank you for now

Mat

Hey Matteo

thank you for been part of this amazing community

Do you want to use an object to get like a shadow pass? or just the lights pass?

there's a bunch of image planes that Mantra can output, let me know if that's what you're looking for

for the destruction question

wait for today's trick 🙂

Hi Varomix,

thank you for your message and for the video on youtube 😉

so... I try to create one mantra node with all light and with the pass like emission and direct (for separate the all light like sky, enviroment, etc...) but I don't want the effect of plane on my alpha so I try to do this:

create a grid->assigned the mantra surface shader->on render tab (geom node) I check the matte shading and no works like I think.

I want catch the effects of my geo light on the plane, but I want my plane has not effects on alpha.

I attached some images maybe help more you

that's great, is looking really nice, yes I saw part 2 on youtube 

is going to look great once you texture it, awesome

 

cloth, yeah, is a bit touchy cause it can be slow, I'll see what I can do

 

thanks

hey MIX!!!!

I continued on more update I try to render and find a good solution on my system, for now I have a very "big question" on glass.

I have a curve glass on the surface and I apply a preset from material shader, but I want know if a good solution or not because I have 2 glass like this

I attached the image of my model

thank you

Matteo

So there is a good tips or way for rendering it better?
