Mac OS X Shaders issues

[RedwanFox]

Trying to play on Macbook Pro Retina early 2013 with nvidia gpu with Mac OS X 10.11.2. Main base and mushrooms are black. Spring engine doesn't generate any log.

A hack to obtain the log:

cd Flove.app
./Contents/MacOS/spring > ~/flove.log

I'm not sure it will actually save the log in flove.log but at least you'll probably be able to see the log output in the CLI and grep it for renderer.

I'd suspect this is it failing to use the nvidia gpu: i get the same on a mac which doesn't have a discrete card.

It seems Spring used NVIDIA GPU. Also, only central structures on map are broken. Trees on the map borders and newly grown flowers are fine.

Grep results:

MacBook-Pro-Redwan:~ redwan$ grep -e "[R|r]end" flove.log
AllowDeferredMapRendering = 1
AllowDeferredModelRendering = 1

Flowers don't receive any shaders, so that's why they're fine.

Hypothesis: this is an issue specifically with the outline shader?

[RedwanFox]

Yup, according to log thats the problem. Most of the log file consists of failed to use GLSL shader messages.

[Anarchid]

The real question, is it outline, or do all shaders fail to compile?

Try modifying the archive Content/share/games/spring/games/flove.sd7 by removing files similar to LuaUI/Widgets/*outline*.lua from said archive.

[RedwanFox]

Removed the only file gfx_outline.lua and reconstructed the archive. Game doesn't start now, saying that it can't find flove 1.1 archive.

[Anarchid]

Possible reasons: archive no longer having sd7 suffix, or archive being solid.

[Anarchid]

Ah, nevermind. The outline hypothesis was stupid anyway: everything would have been affected by that.

Can you post the full log?

From the screenshot it seems that the mushroom and treeshaders are failing: https://github.com/SpringCabal/LD34/tree/master/ModelMaterials as well as the wisp one: https://github.com/SpringCabal/LD34/blob/master/LuaRules/Gadgets/wisp_animation.lua
It may be prudent to raise this with the engine if you could provide an infolog?

Raise @abma @rtri

Spring engine doesn't generate any log.

no, you are looking in the wrong directories. try ~/.config/spring/

without infolog.txt its not really possible to help.

[RedwanFox]

Full log has arrived.
flove.log.txt

[abma]

tons of shader errors in the log file, i guess devs now have something to work now :-)

thanks!

Looks like mac nvidia drivers are for some reason much more strict than both nvidia linux/windows ones as well as those for ATI!
