I don't see the IFX Assembly Sequence Name node in the ICE tree at all. Is there a way to use the standard tools to get it to write out an image sequence based on the frame? I'm not reading a sequence in, I just want to write out my own from scratch. I'm able to write out a single frame which is awesome. :D

This is definitely an awesome plugin!! Thanks so much!

Something else that would be cool to have, is a node that autmatically builds a point cloud in the correct order and a node that builds the color array in the correct order from that pointcloud. Just tossing out ideas.

It is just a simple compound that I builded from factory nodes :)

That is very simply to implement, fisrt case I have attached as compound called "Build PCloud From Image" , and in the second case you can just use "build array from set" node to get array of colors and connect this array to "Write Image" node

Awesome got it working! Thanks so much. Just did a simple setup using a null to modulate the color of particles inside it and output the sequence of the null moving from one side to the other.

I have to say this is really fast as well. Just played back the timeline and it zipped along as if it wasn't doing any extra calculations. :) Great job! Now I just have to figure out or dig up a compound that what pixel particles does and stick some particles to a mesh via UVs and we have a custom "pixel particles" setup.

Also anyone who is thinking of doing an ICE based renderer has an option now too. :)

Man, this is soooo awesome! thanks a lot Mr. Core.
all kinds of image processing inside the ice tree! that's fantastic and will surely open up for a lot of possibilities.

here's a quick image blur test, along with 2 compounds that might be useful to some of you.

"Change File Name" compound: changes or appends file name of a file path input with option to keep or change extension.
(also outputs a no extension string to be fed into IFX Write Image, since it appends the format itself)

"Get IFX File Format from File Path": outputs an integer to be fed into "Format" port of IFX Write Image.
bmp = 0, jpg = 1, png = 2, tiff = 3 (defaults to bmp in case of unsupported file format)


I can't thank you enough!

That's really awesome example of usage! You boosts me to take a deeply look into it, because I didnt spent too much time with the image processing :)

This is fantastic. There are an incredible number of uses, we can use this in a way similar to how houdini users use chops in conjunction with particles etc. Fantastic!

Here's a selfish request, do you see any way to add .exr or .dpx I/O? It would be awesome to be able to do some operations on film plates with this.

Honestly, in the long run I think this will have more impact on ICE/VFX than anything you've written to date - and that's saying something. :)

I think I will add these format a little bit later as well as alpha channel :)
But I still think that it is more a toy than real tool because representation of each pixel as particle and work on this - it is very sloooow way
