Subject: Texture file size question. Again


n0s4ra2 ( ) posted Sat, 23 August 2003 at 12:22 PM · edited Thu, 14 November 2024 at 1:58 AM

I have made a texture 2000 x2000 and the file size is around 8 Megs. I dont want to reduce the 2000 x 2000. What would be the best way to get the Meg size down? Do I save the texture as lower quality? Any advice is appreciated.

Is this for yourself or to distribute? Compressed TIF will save a little harddrive space. JPG at 99% will also save. Photoshop's Save for Web (Image Ready) is excellent for this. Try different compression percentages and see the results before saving. Remember, as long as the pixel dimensions aren't reduced, the space you save on your harddrive has nothing to do with the space it takes up in memory. It will still be 8 megs in memory. I think most people don't realize that a 4000x4000 texture map takes up 32 megs of memory.

I have found through experimenting that if you reduce the jpg from the highest quality setting (12 in Photoshop) to around 7 or 8 (medium to high) there is barely any noticable difference, especially if you aren't doing any extreme closeups.

Spit, that's interesting I didn't know that. I've been trying to find a way to reduce the size of the overall .pz3 file (and rendering time) without sacrificing too much quality. What I have been doing in the past is reducing the size of the texture map and saving the jpg at a medium setting. So are you saying lowering the image quality won't reduce the poser file size?

Photoshop's Save for Web is probably the most efficient way in existence to save jpegs. Even at the maximum quality, it beats most other apps. And you don't need Image Ready to do it. Just press ctrl-shift-alt-s One useful thing to understand about jpeg compression is how it works. A jpeg reads an image in 'areas'. If 2 or more adjacent pixels in a line have the same value, they will be 'bundled' together, and the jpeg will be rebuilt with X number of pixels in each line all having the same color value. This means that the size of a jpeg is highly dependent on the amount of detail you have in it. If you have huge areas of the same color, it will compress well. If it's a mass of tiny details, it won't. mac

Its a texture I made to distribute. I am trying to get the size down so I can redistribute it. I have seen some great looking texture that was not 8 Megs so I figure I made a wrong turn. And I am not trying to reduce the size

If it's 2000 x 2000, that's not extraordinarily big. But without knowing what kind of texture it is, or how you saved it and in what format, it's pretty difficult to give any help. I can only repeat what I said. Save for Web as a jpeg. mac

Its a jpg Part photo leather part hand drawn. I think the save for web or reducing to 7-8 in Photoshop will work Thanks guys for the help and quick response

Save for Web uses Image Ready functions...doesn't matter though since it's included with PS. I probably shouldn't even have mentioned it. pzrite..yes, that's what I'm saying. The texture takes up the pixel size in memory.

Spit, I dumped Image Ready. I can happily live without a memory-gorging piece of junk that does nothing I need and takes about 10 minutes to open. LOL. Mind you, I suppose it depends on what you do in a graphics app. But I'm sorry that Adobe succumbed to the (then) current hysteria for web-oriented apps. After PS 6, I pretty much lost interest in upgrading. mac

I only use IR for the droplets. I batch convert wip files to jpg with it. It's unvelievably fast to do it that way.
