large z3d file doesn't open properly

[rebdamas]

I have an autosave .z3d and normal .z3d they do not open properly. It opens with the textures in the texture browser but the model does not show up. The save file size is 690mb. This is large due to the textures, i did not know they were that big before saving the file.


When opening the Z3d it throws a texture was not found error (even though they show up in browser).

is there a way to fix this, i lost all my progress on this model. Even the old save i had doesn't work. See included pictures, Thanks in advance!

**EDIT i think i posted this is the wrong forum section, my apologies.)

hello.
your file might be already corrupt on save.

I strongly advise to switch to 64-bit version, especially if you work with such a big scene. Mind, the .z3d file is compressed, so the actual data stored there could exceed 3.5Gb which is an application limit for 32-bit app.

Also, I advise to keep textures externally in the same folder. Toggle off "Store textures" option in Settings->General->Files->Z3D Open&Save branch.


P.S. if you have a .bak file(s) in some folders next to saved .z3d, these are actually .z3d files too. You can rename them into some different names with .z3d extension and try to load them. May be you can recover some early stage of your file.

P.P.S. resize the ribbon with commands/buttons vertically, it takes too much of screen space and doesn't use it.

Honestly had no idea I was on the 32 bit version, i'll switch over. That probably explains why i experience so much lag/processing time when attempting to do tasks like UV map, deleting materials, etc. Sadly I already tried renaming the .bak files to z3d they were also causing the same errors. I'll just have to start fresh.


I appreciate the help!

the performance, and UV tasks in particular, will not increase on 64bit.

Hello,
Switching to the 64-bit version and saving textures separately should help with future work. Also, using an online third-party tool like JPEG Compressor can help reduce texture sizes without losing quality.

Thankyou.

it is strongly recommended not to use any other texture format other than .dds
any other texture being loaded will be 32-bit RGBA texture (yet it will have less size when saved on a hard drive as .jpg or .png, but will take too much memory size when being loaded into ZModeler).

Thank you for agreeing. These steps really make a difference in optimizing workflows.
