[Archived - Lexique] 2nd mesh won't cycle or scroll in my avatar attachment

Posted by “Lexique” on March 16, 2023.

Hello again @Drosselmeyer​, well I realize that I was working on assumption and not on actuality. I do this more than I want to admit!!! I really thought that the particle size was a percentage of the texture size. It is only after your confusion that I went back into the program and realized that the particle size is an absolute and not a relative number. So “testing” is only worthwhile if it is in accordance with reality lol. So sorry about the confusion.

Anyway, since my diffuse texture is simply a white square, I left it at 128x128 and changed the opacity to 512x512. And everything stayed the same. However, I assume that it will be automatically resized to fit the diffuse texture, but because my particles are very simple, it’s hard to know if I’m having any effect on the quality of the texture.

The particle evolution system is so much fun to play with. This product I made is quite cheesy but it represents a serious amount of configuration trial and error. Being able to view the particle bounds is invaluable. I registered for the particle class, but since I’m working in Myanmar it’s 5am and that’s when my power is cut. So I’m going to try and see what happens!

Hey @Lexique​, Hmm. I am confused. :P I had a look at your product and it looks good to me. I really like the colors of the particle system and what you did with the rotation!! I am also seeing the cycling animation working just fine. What I am confused by is "none of the particles had changed size like I expected". To be clear, the dimensions of the texture is not going to effect the size of the particles. Only the 'Size' under 'Emission' and 'Scale' under 'Evolution' will affect the size of the particles.

As far as the size of the textures for the cycling animation, it looks like I was mistaken. What I mentioned above about cycling:

• Uses the diffuse texture dimensions
• Cell size limit of 128x128 and max texture of 256x256

This only applies to Material texture cycling and not Particle texture cycling.

Hello @Drosselmeyer​ , I did do as you suggested. The following is my product using a 512x512 white square, with a 512x512 opacity cycling texture with 4 different images.

https://www.imvu.com/shop/product.php?products_id=62946443

Just now I edited the product to use a white 256x256 diffuse texture and a 256x256 cycling texture. Nothing changed, none of the particles changed sizes. So I changed them both to 128x128 and they still remained the same. So I saved my several projects, got out of studio and back in to see if that was the problem. When I got back in, the two projects had merged? I've had that trouble recently. These have come from two different meshes but they are very similar. So I'll mention it in the other forum.

But back to this topic, which is not meshes ha ha. Still none of the particles had changed size like I expected. So now it seems to me that there is no sense in using a 512x512 texture or even a 256x256 textures for the particles because they are all obviously reduced by the program to 128x128. I never got an error or a warning about it though, which would be really helpful if the help tip stated the max sizes. Knowing that, I'll change, as it does spare kb to use the smaller textures.

Hi @Lexique​, Try making both your diffuse and opacity textures 256x256 and see if the texture cycling works. Oh, and if your are making particle textures cycle you need to use the animation cycling settings in the particle not the material. I hope this helps.

@Drosselmeyer​ , I'm sorry to just now be writing back. I am having the awesome privilege of hanging out in Myanmar (Burma)! But I wanted to test what you had written because I had already made a cycling opacity texture that was 512x512 and had been successfully using it. So I have had opportunity to test it on a particle texture. I used the default particle texture and just evolved the colors. I wasn't sure what size this default texture is, i didn't open up the directory or any other sleuthing. I did replace it with my own white 512x512 texture and nothing changed. I have the particle cycling set to 2x2, so each cycle will be 256x256. I haven't tried anything greater than this. But evidently this size is working for particles. However, I haven't tested the sizes for the regular material cycling. That will be my next frontier!

Oh @Lexique​ , There is more to the picture on texture animation:

• There is a cell size limit of 128x128, which means the largest texture you can use is 256x256 (I think). If you use a 512x512, I think the algorithm for the cycling animation expects a max size of either 256x512 or 256x256.
• The animation texture needs to be a power of 2 and I think the cell size does also.

I have not looked at the code but gleaned this by trial and error.

We really need to write this up ... so WE can remember LOL.

Thank you for your response @Drosselmeyer​. It would be nice if this tidbit could be included in the mouseover tip for the animation, that it is based on the dimensions of the diffuse texture. But for me, now I will not forget. Nothing like posting to the world something you forgot to shame you into remembering lol.

Oh. Yeah. I think I have encountered this. I think the texture animation uses the diffuse texture dimensions and not the final composited dimensions of diffuse, opacity, shine, emission.

This was not a mesh problem. I had used a 1x1 texture as my diffuse texture even though the opacity texture was 512x512. I changed the diffuse to 512x512 and that was indeed my problem.
