About this project
What does Mythrais add?

Mythrais is an architectural building mod providing a huge collection of decorative and functional building blocks, including windows, roofs, arches, Tudor panels and beams, pillars, battlements, wall details and much more for making your medieval and fantasy builds more buildy!
PLEASE!!!! MAKE BACKUPS OF YOUR WORLDS BEFORE UPDATING ANY MODS <3
CREATIVE -
For those of you playing in Creative using Conquest Refabricated and other deco mods, such as Victory Mod, my 32x resource pack is linked below. The 32x Resourcepack is now CTM-ready but will require Continuity to be added to your instance. (If you play using the Conquest Reforged modpack, this will already be included.)
32X RESOURCEPACK TO COMPLEMENT VICTORY MOD & CR ETC IS AVAILABLE ON MY PATREON!
Creative players can use the Mythrais Adamantium Staff, debug stick or the WorldEdit/tool cycler to access all the additional block shape variations and colours for each block. **Most blocks have some available variation to extend their uses.
SURVIVAL -
All obtainable Mythrais blocks have loot tables and survival recipes.
Mythrais uses a refined resource system to organise its large collection of building blocks. Vanilla Minecraft materials are first converted into their Mythrais refined equivalent, which can then be placed into a stonecutter to access the relevant Mythrais building sets.
Examples include:
- Wood Logs → corresponding Refined Wood Beams
- Bamboo → Refined Bamboo Beams
- Stone → Refined Stone
- Smooth Stone → Refined Smooth Stone
- Chiselled Stone Bricks → Refined Carved Stone
- Stone Bricks → Refined Stone Bricks
- Tuff → Refined Tuff
- Terracotta and coloured Terracotta → corresponding Refined Terracotta resources
These refined resources are then used in the stonecutter to craft Mythrais windows, arches, pillars, walls, floors, roofs, Tudor components and many other architectural blocks.
Different block families use different refined resources to keep the stonecutter menus manageable. If you're looking for a particular block or want to know which refined material you need, the complete recipe list is available below.
Crafting recipes listed here - https://docs.google.com/spreadsheets/d/1xeWqBR8L0L5vqHGY_HOSDgsnq9-KycHB5qT-lqd1QEY/edit?usp=sharing
Survival players can craft the Mythrais Adamantium Staff with 1 diamond to shift and right-click to change block variations, then right-click again to scroll through the amount, shape, facing, type, colour, alt_colour, age, layer, light, etc.
