Have an issue in 7Gen, what can I do to solve it?

[BryceBro]

Hi yall, newcomer here.
I've downloaded 7Gen and i'm planning to do some custom scenes with some cool walpapers (in .jpg format) i have on my laptop. For that i should use the "background2.vxp" tool, right? Cuz that's what i used to try to make one.
The thing is, i compressed my image (39 kilobytes) and also compressed a depth map i made for it using Krita. I did everything right (i think), but while the mod is being processed, the program freezes, stops working and closes. At the error log it reads "long int too large to convert". What should i do?????

[Plopilpy]

what res is the image? it should be 544x306

[BryceBro]

The two images (the image itself and the depth map) are now both in 544x306.
Here they are in question:




The error keeps happening.

[Plopilpy]

are they both 8-bit bmps? it helps to apply an indexed palette, in this case 3dmm's palette. since krita has no indexed colour support, you can use GIMP. open the image in GIMP, and select windows > dockable dialogs > palettes then right click on the palettes section that opens and import that .pal file. now, hit image > mode > indexed and select that palette in the menu.

that image is hella awesome btw. does "brycebro" imply you use bryce3D?

[BryceBro]

I'll try to do that then. Thanks!
But that applies to the depth map too?

Yes, my username is a reference to bryce3D. But the image was not created by me, i just searched for "bryce3D renders" and selected some images i found cool and that could have potential for a 3Dmm scene. I think i have 11 more of this kind. When i finish the mod i'll link it here.

I tried to import the .pal file into the image through GIMP's import pallete tool, but an error message shows up when i try to do it: "Unknown palette file type: C:\Users\Dell\Downloads\3dmm.pal" or smth along those lines

[BryceBro]

Plopilpy do you have any idea of what can i do to solve this error? (the palette error on GIMP)

[Plopilpy]

did you make a new palette slot before right-clicking on the slot and importing it? it worked for me

[BryceBro]

I did that and it still didn't work. I think there's a problem with the .pal file itself. I tried using other palettes i downloaded from the internet (in .pal files) this way and it worked.

[Plopilpy]

try importing this BMP instead, by opening the BMP and selecting import palette > image

I did that. I converted the two images into 8 bit bitmaps and was successfully able to import the palette. All of this while they are in 544x306. Here's them now:




... but the same error still happens in 7Gen. At the error log it still reads "long int too large to convert". I give up on doing this mod. I'm about to go insane

[Holmstrom]

It's not a palette issue. Even plugging the .jpgs straight into 7gen should convert just fine. Post your error log!

Also, that depth map is not gonna give you the result you're looking for. It's reversed (nearer surfaces should be darker) and way too high contrast.

I'm almost sure that my depth map is right with the colors, but i agree with you about the contrast. I'm gonna make a revised version of it.

[Holmstrom]

You're using a version of 7gen from almost two decades ago! Try grabbing the latest one from here and follow the instructions on installing. Maybe that'll fix it.

Black should represent surfaces closest to the camera while white represents the farthest, so the colors need to be inverted

And yeah, you need to lower the contrast until there's barely any information left. I haven't personally had a lot of success with depth maps in 7gen because of it. A value shift as small as #7b7b7b to #7e7e7e represents an enormous difference in distance, so you won't be able to get a lot of detail with it

[BryceBro]

Thanks a lot!!!!!! I was finally able to get it working!!!!! Thanks!!!!!

And you were also right with that depth map thing. Guess ill have to make a new one
