Before you proceed, notice that this model only contains the TOP of the Octogon (as shown in the renders with the solid grey background). If you want the entire Octogon, check out my other models. If you want not only the entire Octogon but the entire CHURCH check out my other products too because the full church interior is also available for purchase.
Every part of the Cathedral is named the same as its texture. It should be easy to assign the textures. FLOOR parts and FILL WALL parts should receive the corresponding floor (either BLACK, RED or WHITE) and fill wall textures and I recommend tiling these textures as you see fit.
Please note: I will make the church exterior and objects later (confessionals, benches, altars, crucifix...). Future improvements on this church model will be uploaded and updated here.
Please do not use this model in any way that can be offensive to Jesus Christ and the Catholic Church.
