Image Sequence / Multiple Objects (stylesheet?)

[ParticleSkull]

Hey guys,

Any idea on how can I apply an image sequence on multiple objects?

I have this set of grids and a sequence of textures to apply on it but it can't be randomly. My first thought is through stylesheets (like on crowds) but i'm not sure if this is the best approach. (the original setup doesn't have a copysop though, so I can't use stamps)

this is the jpg sequence i have:

Scene file is a attached

Thx

not sure if I understand: do you want one of the texture per primitive?

[ParticleSkull]

Yeap, and it should be in the right order. 1st primitive have the 1st image, 2nd have the second one and so on..

I can't do it one by one because the original project have hundreds of images (it's something like a real life flipbook animation)

How about applying the pictures inside the shader like so?

 

[ParticleSkull]

Thx Konstantin. This setup based on luminance looks pretty incredible!

The shader thing would work fine. In this situation you have 4 textures applied by hand. Do you think is there a way to do it procedurally? I have hundreds (maybe thousends) of images to apply.

I can't use a stamp btw, the original setup doesn't have a copysop.

 

Thx,
Alvaro

does this help? you'll have to adjust the path and of course renaming the texture files properly will help

Thx Dominik! This is exactly what I need.

edit: It's working fine, it was my mistake

For some reason it's missing the number 8. Do you know what it could be?

Also, I'm putting the path on the string like this:
s@takeimg = sprintf("E:/textures/numbers/num_%05d.jpg", @primnum+1);
it's fine to use it like this, right?

number 8 (visually) is missing because there's no texture with it

yeah sure that's fine

[ParticleSkull]

Thx
I'll try make it work with redshift now to speed up the previews.

Dominik, one more thing. Do you think it can work with the uv quick shade sop? I'm not sure how to link the path in there.

Set a primitive attribute to all texture paths:

string path = chs('path');
string name = chs('name');
string ending = chs('ending');
string num = sprintf('%05d', @primnum);
s@texture_path = path + name + num + ending;

Bind them to a texture node within a material shader:

Combine all textures in a COP snippet before displaying them in the viewport:

int fields = int( ceil( sqrt(count) ) );                              // Number of rows and columns based on total primitive number
int field_curr = int( floor(X * fields) ) + int( floor(Y * fields) );  // Current tile number
vector2 pos = set( (X * fields) % 1, (Y * fields) % 1 );              // Position within the tile

// Grabbing pixels from all textures
string num = sprintf('%05d', field_curr);
string texture_path = path + name + num + ending;
vector color = colormap(texture_path, pos.x, pos.y);                  

// Assigning colors
R = color.r;
G = color.g;
B = color.b;

Corrcted version below! Including HIP-file.

You're a genius. I'll give it a try right now, thx!

[ParticleSkull]

It's not getting the right sequence, do you know what it could be? :/

[konstantin magnus]

Thanks for testing ; ) My daggers were not too useful for debugging it seems..

The orientation is probably due to texture mapping. Try setting UV texture node correctly.

For the COP snippet multiply by fields one more time (second line):

int fields = int( ceil( sqrt(count) ) );
int field_curr = int( floor(X * fields) ) + int( floor(Y * fields) ) * fields;
vector2 pos = set( (X * fields) % 1, (Y * fields) % 1 );

string num = sprintf('%05d', field_curr);
string texture_path = path + name + num + ending;
vector color = colormap(texture_path, pos.x, pos.y);

R = color.r;
G = color.g;
B = color.b;

This is what the corrected version should look like (image sequence starts at 0 in my case!):

yeah, now it looks perfect!
I'll give a try on the original scene now. Thank you very much, Konstantin!
