Numivo field tools

Production numbers, without the spreadsheet.

Numivo gives environment and level artists twenty focused browser calculators for textures, lighting, foliage, LODs, performance, terrain, traversal, navigation, cameras and large-world planning. Each tool explains its method, updates immediately and creates a shareable result link. Nothing needs an account, an install or an upload.

Textures & lighting

Density, baked-light detail and GPU texture memory.
01 Texel Density Calculator Work out texel density in px/cm and px/m from any texture resolution and surface size, check it against the standards shipped games use, and get the resolution you actually need. 02 Lightmap Resolution Calculator Turn a mesh's surface area and your target cm per texel into the lightmap resolution to set in Unreal Engine, rounded up to a legal multiple of four, with the detail that rounding actually gives you. 03 Texture Memory Calculator Calculate the video memory a texture costs at any resolution and compression format, with and without mipmaps, and scale it up to a full material set or an asset library. 04 Material Channel Packing & VRAM Planner Compare separate grayscale masks with packed RGB or RGBA textures across compression formats, mipmaps, materials and unused channels. 05 Shadow Resolution & World-Texel Estimator Convert shadow-map resolution and world coverage into centimetres per shadow texel, detail coverage, target resolution and approximate map memory.

Performance & LOD

Frame time, instance cost and distance-based detail.
01 Foliage and Instance Budget Estimate the triangles and draw calls a foliage scatter costs, and see what the same scene would cost without instancing. Inputs are instance count, mesh complexity and LOD behaviour. 02 LOD Distance Calculator Convert LOD screen size thresholds into real switching distances for a given mesh size and field of view, and see how many pixels tall the mesh is when each LOD takes over. 03 Frame Budget Calculator Turn a target frame rate into a millisecond budget, split it across the systems in your frame, and see immediately how much headroom is left or how far over you are.

Worldbuilding

Placement density and dimensions that keep a level readable.
01 Scatter Density Calculator Convert between area, instances per square metre and total instance count, with the average spacing that density produces and real-world reference densities for grass, forest and rocks. 02 Level Scale Reference The real-world dimensions a level has to respect, in metres, centimetres, Unreal units or feet, and rescaled automatically when your character is not 1.8 m tall. 03 Modular Grid & Kit Dimension Planner Check whether kit pieces and target spans align to a shared grid, then find panel counts, exact snapped dimensions and leftover space.

Camera & units

Move values reliably between cameras, engines and DCC tools.
01 Engine Unit Converter Convert a measurement between Unreal, Unity, Godot, Blender, Maya, 3ds Max, Cinema 4D and Houdini units, and get the FBX import scale factor between any two of them. 02 Field of View Converter Convert between horizontal and vertical field of view at any aspect ratio, see what an ultrawide player actually gets, and read off the equivalent 35 mm focal length. 03 Camera Depth of Field & Hyperfocal Calculator Calculate hyperfocal distance, near and far focus limits, total depth of field and horizontal FOV for common virtual camera sensor formats.

03 tools

Terrain & large worlds

Landscape resolution, streaming coverage and open-world scale.
01 Unreal Landscape Size & Heightmap Calculator Calculate a valid Unreal Engine Landscape heightmap resolution, world dimensions, component count, vertex storage and the correct import Z scale. 02 World Partition Cell & Loading Range Planner Estimate World Partition grid dimensions, intersecting loaded cells, resident memory, loaded area and streaming lead time from map and runtime settings. 03 Open-World Travel-Time & Map-Size Calculator Convert map dimensions, route detour, player speed and POI count into traversal time, effective distance, area and average content spacing.

03 tools

Traversal & navigation

Jump arcs, walkable slopes and agent clearance.
01 Jump Arc & Traversal Metrics Calculator Turn jump velocity, movement speed, gravity, landing height and coyote time into apex height, airtime and safe platform spacing. 02 Ramp, Stair & Terrain Slope Calculator Convert rise and run into slope angle, grade, ramp length, stair count, actual riser height and a navmesh walkability check. 03 Navmesh Agent, Doorway & Clearance Planner Check agent capsule clearance through doors and ceilings, voxel erosion allowance, obstacle step height and maximum slope in Unreal Engine navigation.

Why these exist

Every calculator replaces a small spreadsheet someone kept rebuilding. They run entirely in the browser, send no input to Numivo and keep the formula visible so the result can be checked. They work independently from the Numivo desktop toolkit.
