13 vertex by 13 vertex rendering

Mr.Rubinshtein

thought its a culling

AdrienTD

Yeah, no faces are stored, they are implicit

PegPeregoGaucho

and the uvs?

AdrienTD

the UVs are stored

AdrienTD

There is an array of materials, and each material stores flags as well as UVs for the 4 corners of the quad to which it is assigned

AdrienTD

The first material is the water, it has the special property that the game modifies its UVs ingame to make the water flow

AdrienTD

Now, how where the assignment of materials to the faces are, I still have to find it

AdrienTD

The world is transforming into water! :WutFace:

why is it not solid anymore :WeirdWhat:

AdrienTD

I think the byte that indicates the collision type (solid, slide, etc.) is just next to the byte that assigns the texture

AdrienTD

And I was overwritting the whole array with 00s in the memory editor :Pedlar:

PegPeregoGaucho

did you also find it in the rom?

AdrienTD

Yes

AdrienTD

It is compressed, but there is an array for every level that indicates what to decompress with the input address in the ROM and the output address in the RAM

PegPeregoGaucho

what are your plans? make a full blown editor or only to finish the geo export and then move on to something else?

AdrienTD

We'll see
