Title says it all.

Can you elaborate on the problem with Linux? I don't have anyone testing on Linux yet. Would you be able to link a screenshot?

Too many shaders on some of the materials can cause compatibility issues and ue4 (and adk) warn when materials have too much going on in them with textures, etc.
What it causes is some shaders and therefore some textures to not show up.

Now, with that said, it's not just this map. Lots of the materials that wildcard uses also suffer from this issue. Best suggestion I can give is to look at the actual ue4 guides on materials, textures, etc

I'm reading that because linux uses Open GL it is limited in the number of texture samples per material, whereas windows uses DirectX and supports more samples.

The landscape material has more texture samples than linux allows, have you noticed problems particularly with the ground textures failing to render? I can try to reduce the number of texture samples used by the landscape to 16 or below. There are some textures samples from the island that aren't being used by madagascar I will get rid of.

My OS is Ubuntu/Gnome 16.04. with Nvidia 950 .It is ground textures ( maybe more). Where do you want me to send screenshots? All 3 DLC maps work fine...all map mods do not. Steam puts forth that Ark is compatible and is but DevKit is not compatible with Linux so all mods are made by windows users that have no way to cross test a mod. I will help in any way I can.

Thanks chazzmac. It must be the landscape material.

Apperantly there is a way to go component by component in the landscape and reduce complexity. I'll try that next.

10-4...you will make many, many Linux users very happy.: )

How is it going? I hope it does not prove to be a daunting task. I have spent a few hours on your map and even with the missing textures I can tell how well it is put together and am excited about a possible fix for Madagascar. I have Favorited it and will be watching for updates and ready to give my input in regard to the texture problems ; ) Thanks for caring and Thanks for your workmanship.

I've made the jungle grass texture sample, which used to be 2048x2048, 1024x1024. I'm hoping that by reducing the complexity of the landscape material, it will render on openGL platforms. Originally I tried to reduce the number of texture samples being referenced by each component of the landscape. I found out that the components you screenshotted are very complex but they only reference up to 4 texture samples. The complexity is due to the high resolution of the samples. I can't limit components to only 3 or less samples because that would compromise the map's detail.

If I can reduce the resolution of some of the textures enough, then we may have a solution, otherwise I will have to make a map extension which uses an alternative landscape material made for openGL.

One question I have is: Is the entire landscape appearing as gray boxes or only that section where you took the screenshot? Are there any sections of the map that do work? It might be a good example for how to adjust the broken sections.

Sorry to report that the entire landscape is like that. I have found no sections rendering correctly. I can post more screenshots if you like. Trees, water, savanna grass, general foliage, large mesh rocks ,and boulders all look so good! And that beautiful sky.

I watched your video very carefully 4 times and can verify that all seems to be there except ground textures....as far as I can tell :-P

What happens when you play The Island? Does The Island also fail to render the landscape material? Or does the Island work correctly for you?
