3D Model w/ Transparent Textures

Use a custom ModelProcessor to apply effects at build time. But it seems to be very complicated to get it work with the content pipeline builder… it is my main problem while porting my engine from XNA to this version of monogame…
It ran smooth 60fps with instancing, deferred rendering, DOF, dirt lensflare, lit particles, ssao…
And i can’t add an effect on the model processor with monogame 3.5. Maybe 3.4 ?
