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.

I bring you the one and only cave package you will ever need (I hope :slight_smile: ):

  • 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 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 Material.
  • 20 materials for additional props.
  • 16 additional Mat. Instances.
  • 24 water/drip sounds + cue’s.
  • 4 Material functions.
  • 4 decals. (Moss, wetness, Glowworms)
  • 3 Particle .
  • 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 Material:

  • Whole 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 :frowning:

  • 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 .

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.

  • My mother, My biggest supporter. May she rest in peace.

Nice Lous, a ton of great work!

mother of god

This looks quite nice! But FYI your second video is blocked in the USA for copyright (presumably audio).

If you don’t support this, you’re a fool.

Which I mentioned in the post, I am currently updating it with a song that wont be blocked :slight_smile:

Thou Plaid hast spoketh! :stuck_out_tongue:

Thanks Allar! (and others)

Exactly what I was waiting for and getting ready to build myself, thanks!

Oh wow this is amazing, I would buy this for the 80$ in blink of an eye! Great Work!

Sweet! Finally got it up on the marketplace, can’t wait to vote / buy!

I know you like rocks… but in reality, you’re more of a CaveMan… :wink:

Looks great bud!

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

I want to buy this!

Awesome work :slight_smile:

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 :wink:

Great work Yoeri!

I am Charleston Silverman and i approve this message. :wink:

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

I need this in my life now!

1.Since the meshes use a rather different technique (4 UV maps, one being the lightmap, another being a setup for Normal tangents) that is a rather tedious thing to do.
You can always export the mesh and render one out yourself. The advantage of this pack is that you dont need custom maps, just make a seamless texture and it will work.
2. No, they use an intriguing setup of vertex paint, multiple uv channels. no unique maps needed.
3. To quote my original post:

  1. You can check the package out in a special VR demo made by Jan Kaluza: (which was also mentioned in the innitial post).

there are actually two detail roughness and one detail normal textures in the material setup.
You can also manually scale the textures to your liking.
Hope that VR-Demo helps :slight_smile:

Charleston for president!
PS: Would loooooove to see your materials on my rocks! [flirt]wink[/flirt]
Not kidding guys and girl, Charleston makes the most awesome materials! they will work awesomly on my cave-package!

bangs head on rocks Lu-sapien like taste of rocks against head!
scratches chest

I hope this package will provide you with your cave-needs.

Awesome to hear! thanks :slight_smile:

No you are awesome!

And hopefully soon you can!

hmm? care to eleborate?

It would be kickin awesome to one day play an rpg and think to myself… hmm… these caves look… like mine! OMG!

I would loooove to have a liondog in my life, I mean… look at them:

Updated main post to add this:

It shows all the options available in the material instance.
If you enable “use texture for snowcaps” & “use texture for snowcaps roughness” it will open up an option to add an additional diffuse and roughness texture for i.e. moss, ashes, images of cats.

It’s been a long time coming, and I’m excited to finally see this make its way to the marketplace! :slight_smile:

As Yoeri mentioned, if you want to see a beta version of this package in action, check out my Flowstone Cave Experience! It’s free :slight_smile:

Yea… to iterate on the last suggestion:
Seamless cat images also work:

I… should go do something more productive now.
