Scatter texture?

[DanSHP]

Lets say I have a procedural radial gradient ramp, that is set not to tile. I apply this to a plane. The radial shape is displayed on said plane once as I have set it not to tile.

Now, what I would like to do is take that procedural radial shape and repeat it across x area at different sizes and opacity's in a procedural manner. Is this possible in 3ds Max? Script perhaps?

Try the OSL shader.

Yeah, OSL I thought as much.

Time to get stuck in...

So I've spent a fair few hours looking into OSL. Very interesting.

What I'm trying to do essentially is create a procedural water ripple normal/bump map (that I can animate as a goal eventually), but I'm struggling to blend in the randomized bitmaps over one another. The first thing that comes to mind is to blend one instance of the bitmap via add over the base bitmap, but I'm not sure how to do this in OSL.

Any ideas?

Is the input bitmap a PNG? Because in the OSL sample about randomizing bitmaps, it's a PNG with alpha channel. My bet is you need to have an alpha channeled bitmap.

Good shout!

[DanSHP]

Very cool. Good start.

Cool, can you use an animated texture?

I've had a look.

I've been trying to load in a set of png's via the max bitmap loader node in slate (as a sequence), but I can't seen to connect this to the OSL randomizer node and get an output to my material bump slot. It just doesn't load in the Randomizer at all loading this way.

The only way i can load a bitmap into the randomizer node is to click on the file name radio dots and load it that way (filename00 etc). The problem with doing it that is that you cannot load in a sequence.

In the video he slots a bitmap node into the randmoizer input slot, but this this doesn't seem to work for me. I'm clearly missing something here.

I wonder can you use a gif with alpha channel? I don't have access to max 2019 or above so I can't test it.

[DanSHP]

I'll have another look tomorrow. In the mean time attached is the max 2019 file if anyone else wants a look!

Manged to achieve the effect I was looking for using a Blur Studio plugin called Rain. Super easy.

Should've used a zillion particle RealFlow sim!
