Preview and pay for a conversion
Open Company Information > Convert a Mek and select an existing unit. Search its family, then select a replacement to preview the price. Only the company owner or GM can convert it. A unit in a locked unfinished track must finish that track first; destroyed equipment cannot convert.
Classic/Override uses base BV as the SP price; Alpha Strike uses base PV times 40. Standard sale credit is half the original price. Subtract the credit first, then apply the published-model percentage plus the configured painted-model percentage when a free eligible model is available. The published percentage is 25% minus one percentage point for each year until the variant introduction, floored at zero. For example, a 3050 variant receives 24% in 3049 and 25% from 3050 onward. The discounts add; they are not applied sequentially.
For example: original 1,500 SP, replacement 2,000 SP. Sale credit 750 leaves 1,250; a combined 40% discount leaves 750 SP to pay. Cost cannot go below zero and no surplus sale credit is paid out.
An assigned matching physical model is reused. Otherwise an available matching model can be reserved during conversion. Printable designs do not qualify. A GM-confirmed outside-model exception does not grant the discount. Model status shows unresolved preparation or links; the GM handles specific corrections.
Pay and convert posts one net debit and saves an itemized receipt. The unit keeps its ID, pilot, damage, deployment and historical relationships. Conversion is not a repair. Draft rosters synchronize; locked history stays unchanged. Stale quotes and repeat submissions cannot charge twice.
Campaign custom designs
Open Company Information > Campaign custom designs and upload a BattleMech MTF or BLK file, up to 1 MB. The original file and its SHA-256 are saved with the campaign; other company owners in this campaign can browse and use the design in conversion. It does not enter other campaigns or create physical inventory.
Every uploaded design remains custom even if its name or MUL identifier resembles a published unit. It never receives a published-model discount. The 15% physical-model discount can still apply. Unpublished local designs must be uploaded before use as a custom conversion target.
The web upload reads metadata, not construction legality or calculated combat values. If the exact file hash matches an already imported design, known base values are reused. Otherwise the GM downloads the original, verifies it in MegaMek/MegaMekLab, and records base BV/PV and calculation evidence on its review page. Unknown values block conversion; PV is never inferred from BV.
Use the custom design by selecting it in the original Mek’s family. Its family, verified values and price are checked again when the conversion is saved. Pilot skill does not alter these costs.
