Tombstone 3D Modeling & Renders

I have an online store that sells custom tombstones and I need every product shown as a realistic, web-ready 3D model. There are 15 distinct shapes; each shape must appear in four different stone finishes, giving a total of 60 textured variants.

Purpose
The models will be embedded on the website, so file size and clean topology matter, but they still have to include enough detail to showcase polished edges, bevels and the engraved name plate area. Think medium detail with engraving: no microscopic chiseling, yet clearly readable carvings when a visitor zooms in.

What I will provide
• High-resolution reference photos of every shape from multiple angles
• Close-up shots of each granite / marble texture and its exact colour tone

Scope of work and deliverables
• 60 individual 3D files, UV-mapped and textured (preferred formats: glTF, FBX or OBJ—happy to follow your recommendation)
• A separate PBR material setup for each of the four finishes per shape
• At least one clean render on a transparent or neutral background for every variant, suitable for the product gallery
• Source files retained in your native package (Blender, 3ds Max, Maya, etc.) so we can edit inscriptions later if required

Acceptance criteria
The models must display correctly in a WebGL viewer without obvious shading artifacts, textures must match the provided samples, and engraving depth should remain consistent across all variants.

Once the first shape is approved, the rest can follow in batches to keep feedback quick and predictable.
