Thanks for the info, a pity that Half-Life has the pev->body hardcoded in the client-side to 1
CStudioModelRenderer::StudioDrawPlayer()
PHP Code:
if (!(m_pCvarDeveloper->value == 0 && gEngfuncs.GetMaxClients() == 1) && (m_pRenderModel == m_pCurrentEntity->model))
m_pCurrentEntity->curstate.body = 1;
