FAQ - mchorse/blockbuster GitHub Wiki
What is the difference between blockbuster.steve and blockbuster.fred morphs?
blockbuster.steve model morph uses 64x32 (pre-1.8) skin format, while blockbuster.fred model morph uses 64x64 (1.8+ with skin overlays) skin format. In addition, blockbuster.alex is basically like blockbuster.fred but with 3 pixel wide arms.
This section of commands page could be useful if you want to convert your Minecraft skin between these two formats (steve and fred).
Is there a way to fix structure morphs being transparent with shaders?
Unfortunately, there is no way to fix it.
My screen is shaking when MorePlayerModels (MPM) mod is installed. How to fix it?

My model looks weird, its texture looks stretched... How to fix it?
Well, there are two possible scenarios:
You used the wrong model morph for a skin
Depending on the way your model looks like, let's take a look at this exhibit:

- A. INCORRECT:
64x64skin was used withblockbuster.steve(which supports only64x32skins) - B. CORRECT:
64x64skin was used withblockbuster.fred - C. INCORRECT:
64x32skin was used withblockbuster.fredorblockbuster.alex(which support only64x64skins)
The fix for this is to change the model. Either reconfigure the morph from scratch, and give the correct skin, or edit the morph, and just pick another model like shown here:

BSL/Complementary shaders bug
If that's an issue that arises only with BSL based shader packs, then the solution is to disable an option Visual > Resource Pack Support in BSL's/Complementary's Shaders Options:

If that didn't help. Try also disabling Visual > Normals & POM Config > Parallax Occlusion Mapping.
