    After about a year of on and off work (give or take 5 - 6 months if I dont count days off/rl stuff) I think I am at a point where this is ready to be released.

    Luos's Modular Rocks & Cave package!

    Current Status:Released! check it out at thank you!

    Estimated Price: $ 74,99

    So what is in the package?
    *deep breath*


    Main Content:
    - 485 meshes.

    - 79 of these are modular cave meshes in 5 catagories (813 polygon average)
    - I-shaped corridors & rooms.
    - L-shaped corridors & rooms.
    - T-shaped corridors & rooms.
    - X-shaped corridors & rooms.
    - Additional sections.

    - 406 of these are rock & prop meshes in 11 catagories. (2100 polygon average)
    - Rocks.
    - Columns.
    - Arches.
    - Stalagmites & Stalactites.
    - Floors.
    - Mesa's.
    - Spires.
    - Walls.
    - Crystals.
    - Mushrooms.
    - Additionals.

    - All meshes come with:
    - Collision <> Updated! Improved Collision complexity between 20 - 90%!
    - Proper lightmaps
    - Modular meshes have sockets at each entrance. (easy when you want to use blueprints on them)
    - Modular meshes already set up for a future spline tool Jan Kashaar is working on, and helps if someone wants to create an auto cave-system generator.

    Material details: (for caves/rocks only)

    - Number of Master Materials: 1
    - heavily customizable.
    - can use any and all arbitrary tiled textures.
    - Automatically rescales Uv's to the world scale of the mesh.
    - Optional directional blend Moss/Ice layer.
    - Optional checkermap.
    - Well documented.

    - Number of Material instances: 253+
    - Many, many options available.
    - Each option will explain what it does when hovering over it.
    - Very versatile, easy to enable and disable whole parts of it.
    - Set up for all 30 texture sets.

    All Mat-instance options:

    Texture details:
    - Texture resolution: 4096x4096.
    - 32 texture sets.
    - some additional props have lower resolution textures.

    Additional Content:
    - 8 example levels. (realistic, fantasy, indoor, outdoor)
    - 1 simplified version of main Master Material.
    - 20 Master materials for additional props.
    - 16 additional Mat. Instances.
    - 24 water/drip sounds + cue's.
    - 4 Material functions.
    - 4 decals. (Moss, wetness, Glowworms)
    - 3 Particle effects.
    - 7 Blueprints.
    - 2 Bokeh's
    - 1 Dirtmask.
    - 4 tutorial videos on youtube.
    - 2 timelapse videos on youtube.
    - And some other little things.


    Additional information about the Master Material:

    - Whole master material is well documented so if you want to go in and check it out its easy to see what does what.

    - All options in the Material Instance have descriptions.

    - You can use any and all arbitrary tiled textures. (Seamless textures)
    This means that you only need up to two different textures for ALL the meshes. (Think of the Vram space you are saving!!!)
    This also means that if you make a seamless texture, purchase one from the marketplace or get one from any other location, it will work on these meshes!
    To give you an idea, look at the following image.
    The first shot is one of the example cave's that comes with this package as-is.
    The three shots after are using the "Naturally Tiling Texture Pack" which never got released

    - The textures automatically rescale with the world scale of the mesh, which allows for fast, easy and extremely versatile environment creation.
    This means that even the slightest change in scale will alter the look of the mesh as well!

    - The material also contains an easy-to-use directional blend layer to create moss or ice effects.


    Other information:

    - Can be used for realistic and fantasy themed caves.

    - Make massive cave systems in mere minutes: (Easily snap to grid)

    - In theory can also be used for sidescrollers/top down.

    - All of the contained 32 texture sets (each containing Albedo, Roughness, and Normal maps) textures are provided at 4096 resolution, some additional props have lower resolution textures.

    - Also included are 7 showcase levels, with one created by beginner environment artist Will Chambers and one created by experienced designer Jan Kaluza (from ) to show the versatility and ease of use of this package.

    - Various video tutorials explaining how to use the package, as well as information about the master material and such. These videos can be found here:

    - Two Timelapse videos showcasing the ease of use of this package:

    - About the Tessellation, I did add a "test" version of the tessellation version of the master material so people who have the package can take a gander at it.
    It might never become a fully supported feature due to the way the meshes & shader are set up though, but I'll do my best and hope that there will be some answer-hub support on the questions I asked.

                  Fully agree, this is one of the most elaborate and detailed packages for UE4. Incredibly awesome work Yoeri! YOU ARE AWESOME. <3

                    I want to buy this!

                    Awesome work Luos


                      These are going into the Indigenous island cave system for sure. Excited to see them on the marketplace!


                        One small request:

                        Could you include UVW maps (rendered as .png)? This would go a long ways to create custom maps.

                        And a couple of questions:

                        - Are these normal-mapped only, or are do they use a combination of normals, displacement+tessellate, and an LOD system?
                        - Speaking of an LOD system, do the meshes have LOD's?
                        - And speaking about LOD stuff, how do the materials look when viewing from very close up? Having several issues now with some assets that, well, need better textures for VR.

                        As you can probably guess, quality visuals with quality performance is a huge trait I'm looking for

                            Yoeri, this is an Epic contribution to the Market Place. I hope it sells out!

                            You mentioned Fantasy caves, and these look perfect for dungeon runs! Anyone who is making a Fantasy MMORPG will definitely have use for these caves! I can't wait to see what people do with this! ;D
