salut,
le 1er numero d'une serie de code dont le but est de faire des décors naturels
pour la v1 c'est le minimum syndicale
(juste 140 lignes de code en plus ma biblio)
parmi les nouvelles fonctions de la 5.70, j'utilise ici :
- CreateDataMesh
- CameraReflection
pour la V2 on aura le terrain illimité
Code : Tout sélectionner
