Hi every one, since January 2013 I habe an SAM460ex. Almost all sofwares which were installed on my A1 work but LodePaint causes a problem: when I launch it the error message "Unabe to set video. SDL error message : failed to create minigl context".

Someone could help me ? minigl/opengl are installed (like my A1...).

Thanks.

Nic

Your GFX card (Radeon HD?) probably doesn´t support 3D accelleration (yet). Try install Wazp3D, maybe it will work.

if Wazp3D doesn't work, try SketchBlock and I'm sure you'll be pleasantly surprised.

Thanks. It works now but ugly... the card is a PCI radeon HD4650 (RV73).

I've also installed it :) I like to try if softwares which works, which not. I also have installe perfectpaint, tvpaint and personalpaint :).

In my SAM, LoadPaint won't be used anymore.

I think sketchblock will become soon a must have soft.

Give lodepaint another try once your graphics card has better drivers. It's a great bit of software.
The "ugliness" is probably due to using software rendered gl/wazp3d. It (wazp3d) is great to have for machines without 3d drivers, but it tends to give pretty bad image quality compared to a proper gl implementation.

Having said this though, I must admit, despite it being a pretty decent package, Lodepaint's presentation leaves a bit to be desired.

edit: actually, I just now remembered that even warp3d itself gives pretty ugly image quality compared to a proper gl implementation. Has been a while since I had a hardware accelerated warp3d machine so I forgot how ugly amiga oses hardware accelerated 3d is. It's possible that wazp3d actually doesnt look any worse.

@fishy_fis

exactly. you are not doing alains work justice. i have had a lot of comparison between warp and wazp3d way ago and in many cases wazp was more acurate.

@wawa

Many Thanks

I remenber that Lodepaint was working with Wazp3D/WinUAE so it may works too with OS4 (but I never tried...)
(Anyway you should better use a real Amiga paint program for 68k with the OS4 JIT)

Delete Wazp3D.cfg and set those settings should help:
Use Renderer: Soft to bitmap
Texture:GL Coloring
Perspective: No (fast)
Use Clear Image: OFF

Compositing should not be used in this case as it is unable to draw a "colored" texture

Alain Thellier - Wazp3D author

Note: if you wanna use Wazp3D to the max with an OS4 machine then try FPSE + gpuw3d plugin or Hurrican

@thellier

i m not even sure where my 68k port of lodepaint even is. i might try to have another go at it one day, but its os4 that is a subject here, and its version of wazp, that is likely more advanced.
