We start from the top view
We then scatter several cubes all around
change Z
Join all of them together control + J
Scale set to 1
this is the best mapcaps for sculpting
remesh shift + R and control + R
we can flatten out the edges
We need a flat top and bottom
We can create strips with the clay strips brush
remesh fine
mesh filter plu smooth setting on
click on the screen and drag
use the draw brush
Add a new texture
to edit the texture we go in the texture option
We then open up a new texture
On texture.com we can type rock brush
click open texture
using it straight away it doesn’t look good
back to the brush settings
save the brush
stroke method
I can then click and drag
reduce strenght
we can add a new brush (texture)
Now from the high poly I want to create a low poly model where I can bake the texture on top of
Duplicate the high poly and leave it on top of the other one.
Add decimate to the low poly object
shade smooth both of them
we can inspect the mesh now
we can now press GG to edge slide the vertex on top other one for auto merge
we are looking for very thin triangles
Now we can unwrap the low poly mesh
we have got some strange holes in the unwrapped mesh
we can do it differently by marking seems. the shape of the rock is similar to a cylinder. use control + left click to mark the lines
we can add a new seem to reduce the size of the long one
re organise the UV
We can now measure the distance of the bits that stick outside the low poly mesh to setup the ray
now we need a new image for the texture baking
create a new material
now we need the just create image texture to be into the material too
select hp and lp last
I need something in the middle
we now have baked the hp texture onto our lp object
we found a little glitch
increase the extrusion distance
glitch solved
save the texture
Now we bake the cavity texture.
Select the hp object and create new material
rock hp
add a input geometry
add color ramp
set 0.4 for black and 0.6 for white
hide low poly, set cycle viewport
it looks good
now we need to go back to the low poly object and create a texture where we can bake the cavity onto
create new image
add new image texture to the material and select the cavity image
change bake type to emission emit
select the hp for a while
select the color ramp and control + shift + left click
we are ready, select both and lp as last
cavity texture selected
ready to bake the cavity
save the image
when done we can hook up the texture to the base colour of the lp to see how it looks like
Now we are ready to paint the rock
When making the water, put the roughness to zero and enable the screen space reflection in the renderer
to create some wave distortion
we can reduce the strenght of the bump
Then we plug the curvature of the multiply node into the factor of the two mix
