Stochastic flakes plugin, take 2

[vlado]

Hello guys,

Here is an updated version of the stochastic flakes plugin; this version is faster and has the ability to generate colored flakes, also has triplanar mapping for objects that don't have UVs. If you think that some other types of controls will be needed, please let us know.

Best regards,

The tripanar mapping thing is very interesting generally - do you think it's possible to decouple this from the flakes plugin and add it as a mode inside of vray hdri, if it has some kind of angle based masking that'd make it applicable for general mapping of bitmaps similar to what Neil blevins was asking autodesk to add in?

[super gnu]

yes please! (+1 etc.) id love it if vray could do the whole triplanar/blended box thing on bitmaps. Neils thing works fine, and i use it ALL the time, but its fiddly to set up and control.

Is it possible to have a link to what Neil did please ?

It's really an autodesk problem and not a chaos group one but if they've already done the work and it'd be trivial to implement it'd be very much appreciated

Stan - here's paul neale doing a video demo, Neil has a written tutorial called "Blended box mapping" on the subject - https://www.youtube.com/watch?v=ILRy4yCXYSs

Maya already has tri planar mapping and the substance material generation tools are including it too, it's a very convenient way of using bitmaps without needing uv's and avoiding stretching.

[vlado]

Well, our mapping doesn't do the blending part (neither does the Maya implementation, actually). It might be possible to do an OSL shader for this though.

I've really gotta look into OSL after this week - there's some really flexible stuff being done in it. This is definitely a gap on autodesk's part though, I'll pop it up on their 3dsmax feedback site and give the eue attending members a poke.

for Stan:

his script (i use the UVW map method) is included in the soulburn (formerly blur) scripts pack .. and if you dont have those... -nope. impossible. i couldnt get by a day in max without soulburn.

[vlado]

Actually I couldn't find a way to do what I want with OSL, but I'm almost done coding a C++ plugin... will post it here hopefully later tonight.

You're like santa except leave presents multiple times a year. I've no idea how you achieve all you do with the company and stay as healthy as you are too, you're a very impressive person Vlado.

[super gnu]

holy cow. ..as above.. Vlado.. do you sleep?!

Uuuh, now you've got my attention!

Here is an early attempt. Please test it and let me know if there are any issues or if you want anything else added.

In the example images, no procedural textures were used - just bitmaps.

[EDIT] You need to copy the .dlt file to the vrayplugins folder, as mentioned in the readme, not the plugins one.

[EDIT] I was asked to provide an alternate download link as some forum users can't see the attachments...

that looks like just what we are hoping for! buuut, hm.. i copied the DLT (2014) to my plugins folder, but when i start max i get an error: dll blah blah vraytriplanartex2014.dlt> failed to initialise. error code 126 - the specified module could not be found.

what are the prerequisites? i have max 2014 and vray 3.20.03

[vlado]

Hm, I built it against the nightly builds, probably that's why. I will recompile for the official builds tomorrow.
