    [TUTORIALS] Photons Be Free: Mini-tutorials and other curiosities

    Hello Everyone!

    I've been wanting to do this for sometime and just now getting around to organizing and getting some mini projects and things together. Instead of just posting a bunch of random threads with a bunch of scattered bits of information and tutorials I'd rather have them as one cohesive growing piece. Plus, it's such a chore to keep track of so many different threads!

    As many of you know, I typically answer a lot of questions regarding APEX Destruction. A lot of these mini-tutorials, projects, and nuggets of information I post here will gear more towards that side of things.

    I'll try and keep this as organized as possible and will update as often as I can.

    Feel free to throw suggestions my way. I make no promises and keep in mind that I'm not a master of all! I have my own specialties so asking me to show you how to make an advanced cover system, animation, or complex blueprint functionality probably won't get you that far.

    Useful Free Software:
    1. Path Length Checker : Good program for checking the file path length for your project if you're running into the 165 character length issue that causes a build to fail. NEW

    Personal Website:


    1. Colored Translucent Shadows (4.5 or later required)
    2. Sample with Line Trace and Physics Projectile for Destructibles (4.6 or later required)
    3. Destructibles Chunk Paremeters Comparison Testing (4.6 or later required)
    4. Simple Jump Pad Blueprint (4.4.3 or later required)
    5. Night Vision Post Process Material (4.4.3 or later required)
    6. Radar Pulse Post Process (4.4.3 or later required)
    7. Gregdumb's wiki tutorial for Day Night system (with some tweaks) (4.7 or later required)(UPDATED: 3.9.15)

    6. Using "Impact Resistance" for better damage effects (ie. glass vs. concrete wall)
    7. The power of using World Support
    8. Damage Spread

    Other How-To's:
    1. Setting up Local Multiplayer
    2. Setting up and using Cloth with the PhysX DCC Plugin with 3Ds Max
    3. Creating Level of Detail (LOD) meshes in 3Ds Max for UE4
    4. Light Functions with Color
    5. Custom Collision Demonstration - Beginning to End
    6. Blueprint Clock:
    a. Basic Clock Movement
